I can remember when I was 5 years old and had formulated a theory of how electric motors worked. I got as far as electricity, currents and forces but how the forces "knew" what to do was a mystery to me! So began a career in electronics. In the last 23 years I have been involved in product development, embedded software design, engineering management, technology and innovation management, marketing and business development.

In short it has to date been a rewarding and fascinating time. As a self confessed techie, I love being involved in the latest and most interesting innovations, especially those impacting our everyday lives

Whyalla Cuttlefish Weekend, 15th May '05

I have been a SCUBA diver for more than 18 years now and in that time have had the opportunity to dive extensively throughout South Australia. I've dived elsewhere and yes, tropical water is wonderful but my soft spot is for the dramatic offshore waters of Australia's Southern coast. It may be cold but the dramatic scale of walls, caves, ledges, kelp, dolphins, seals, reef fish, oceanic pelagics and the odd rather too large for comfort predator make for what South Australian diving stands for!!

My favorite dive location is Allthorpe Island off the coast of South Australia's York Peninsula. My favorite shore dive is Chinaman's Hat, again on South Australia's York Peninsula.

I wish I could say how many dives I have done but for 10 years I kept no record of my diving, an oversight I now regret, many hundreds I'd say at a pinch! I now teach others to dive and my enthusiasm for the salty realm is as strong as ever.

I have been involved in this mad sport for nearly 20 years now and can be found at the bottom of the pool on a regular basis. We play weekly at the Adelaide Aquatics Centre with formally organised teams and games. After the game you will almost certainly find us continuing the proceedings at a nearby watering hole!

Underwater hockey is very similar to field hockey in the way it is played with 6 players in the game per side and 4 players as interchange. We use a puck which, although looks like an ice hockey puck, is made of plastic coated lead. The hockey stick is very short, about 20cm long and is held in one hand. The entire game is played at the bottom of the pool while holding your breath!

Underwater Hockey started in England in 1954, but it was not until 1984 that the first World Championships took place in Chicago , USA where Australia made a clean sweep in Men’s and Women’s winning in both team events. Australian Open UWH Championships were held in 1975. The Women’s UWH Titles commenced in 1981, with the Junior UWH Championships commencing in 1990.

I could could tell you a bit about who I am but I'm afraid the story would be obsolete before you get to read it. So let me give you a little of who I am at the time of writing this text. I am having a rich and adventurous life, full of "life experiences" as they say and it is my intention to keep things that way!

I presently live in the quiet city of Adelaide in South Australia. Adelaide may be quiet to some but believe me, there is plenty here to keep anyone thoroughly engaged, enthralled and occupied! You might just have to put in a bit of effort to find it sometimes!

My most recent passion has become the pursuit of excellence in teaching scuba divers. For me it has been a wonderful experience in bringing the brand new uninitiated into a world I have had many privileged years to be part of. Such a stark contrast from my previous life in the world of electronics, technology and computing.

That all being said I am still a technologist at heart and keep my ears to the ground and my eyes out for the latest, the greatest and most fun new things to play with. Today's new ideas may seem like fun and folly for the early adopters but history has shown that the future depends on us. If it were not for our insatiable appetite for ever new and more complex things to fill our lives with then I'm sure we would all still be living in caves and wondering "is this all there is!!".

I wax lyrical about Port Noarlunga Reef at every opportunity. It is not only one of Adelaide’s closest dive sites but also amazingly diverse in what can be experienced.

One of my favourite dives here is in the deep gap that separates the north and south sections of the reef. Simply called ‘The Gap’, a complex maze like structure of limestone bommies, makes its way south from the northern reef section down to a sandy, silty base around 16m before climbing back up to the southern reef section.

The Gap is a wonderful place to explore full of large limestone boulders adorned with sponges, gorgonian corals, and algaes. Large schools of silver drummer and white trevally dazzle while big dusky morwongs more than a meter in length raise the heart rate just a little as they appear out of the gloom or from behind bommies. The gap is also a great place to get completely lost unless you are diligent with good compass work.

At night a dive in the Gap takes on an eerie other worldly nature. Bommies become giants with manes of flowing kelp lurking in the dark. Every flash and flicker of silver in the distant light of the torch-beam makes my heart skip a beat or two. The sand is alive with molluscs while littered remains of crab mark the last meals of a nearby octopuses.

On Sunday night’s dive I found nestled in a challis-like sponge this beautiful black cowrie with its shell of mottled gold. So named ‘black’ as their black mantle hides the polished shell beneath. This one is feeding on the algae that covers the cup of the sponge. I have noticed cowries feeding like this in bowl like sponge structures on previous dives. Perhaps the silt collect down deep in the gap promotes the algal growth and attracts the cowries.

I finished the dive with the long swim back to the jetty, to fresh air and to the quizzical looks of passersby as I emerged from the inky black water in the torchlight. If only they knew what was down there. Gold!

This was supposed to by my first dive on January 1, 2022 but … It is true that no plan survives long into its enactment and on this occasion technical issues delayed things and I finally got into the water 6 minutes after midnight.

I had two objectives for last night’s dive. Find an Apple watch rumoured to have been lost off the jetty during the day and find some interesting things to photograph.

After about 20 minutes of serious watch hunting I gave up and reverted to critters. The first really interesting encounter was a common octopus about the size of the two of my hands together. We entertained each other for about 5 minutes before she invited me back to her lair. Unfortunately without a bite from Wonderland Alice’s cake I was never going to fit through the tiny entrance.

Then I noticed a baby Port Jackson shark resting on the sand and the photo session was on. For the next while I discovered 3 more baby sharks, flounder, flathead and numerous crabs of all shapes and sizes.

Later I found myself enamoured by a massive school of small bait-fish which shimmered and flashed in my torchlight as they moved like a murmuration of silver starlings in the dark and led me to … an Apple watch lying quietly in the sea-grass. Imagine my surprised when I picked it up to be greeted with its wallpaper image, the time and battery remaining!

Post dive, Apple watch and owner have been reunited and I got my ‘Baby Shark’ photograph.

There is something both beautiful and terrifying about comet Leonard’s appearance in our evening sky. This time last year no one knew it even existed.

For the last 40,000 years the comet has been hurtling inbound from the depths of our solar system on its 80,000-year orbit. Greg J Leonard discovered this expectant visitor back in January and his namesake finally became visible to the naked eye this month.

Beautiful because visible comets are a rarity in our night skies. Terrifying because we had no prior knowledge of its inbound journey and then how terribly close to earth it came. It is a reminder that we have no idea what is out there coming for a visit and very little time to react when discovered.

This time, astronomers and stargazers around the world got to see comet Leonard as a delightful visitor to our solar system and to our night sky.

It’s the night before Christmas and a man walks alone along a solitary Galway alley. The lights in the shops now display gifts that could have been. More likely they will be snatched up in the post-Christmas sales when their value as tokens of love and affection has passed by for another year.

Whenever I see someone walking alone on Christmas Eve I wonder what their story might be. Is there a loving family somewhere waiting for them? A friend perhaps, or some other welcoming destination just a little further on. Or maybe they are just biding time before Christmas day.

I wonder because as long as I can remember, Christmas Eve has been my family’s time to get together and enjoy each other’s company. I am so grateful we have always been able to do this.

So on Christmas Eve I would like to take this opportunity to thank every one of you – family, friends, acquaintances and passersby – who, despite another difficult year, have made our lives just that little bit richer and given us the opportunity to do the same.

Happy Christmas and may the New Year bring hope, joy and happiness to you all.

Well actually if you go hunting you will find quite a few more! Yes I’m back at the Gilman Wetlands again on a typical evening home commute.

I am drawn to these abstracts, the hidden perspective that thousands of people drive past everyday without ever realising its there.

Sometimes I come here and see nothing out of the ordinary. This time two pelicans and their sunset shadows caught my eye.

Regardless, it’s always beautiful.

The planet ‘Kelp’ is hidden to the sight of most as it hides just under the waves that kick up on Aldinga Reef. Divers know it but often overlook it’s beauty seeking instead the grandeur of the nearby ‘Drop-off’ down to the sand below.

I have always loved this part of the Aldinga Reef system with its torturous maze of ledges, swim-throughs, holes and tunnels. The limestone structures provide refuge for fish nurseries as well as habitat for critters that need the cover of cracks and kelp.

You can linger here protected, exploring all those nooks and crannies, even as the fierce gulf current picks up making the outer reef challenging. The shallow water makes it possible to spend a long time before needing to return to the ‘dry’.

Planet Kelp’s crowning glory though is that amazing canopy of yellow-green kelp. It’s just gorgeous making this place come alive with movement and colour.

Can’t wait to visit again soon.

By all accounts it was one amazing day out on the ocean. Our first real day of summer and sea conditions that were nothing short of perfect.

Our plan had always been to venture South to the incredible Aldinga Reef system and dive that infamous drop-off if conditions permitted. Not only did the conditions permit, they invited!

Dive shots with 15m visibility to come later but I had to share this image of our tiny section of drop-off.

To give a sense of scale here the yellow green kelp is at 5 meters, the dark blue-green shadowy band behind us is around 12 meters deep while the pale white sand lies around 17 meters. The drop-off is not deep by many standards but perfect to create an immensely grand sense of scale underwater.

Every South Australian diver would be very aware of Aldinga Drop-off’s ‘infamous reputation’ so I will not go into the details but for my land locked friends this site has had two high profile Great White Shark attacks. One attack resulting sadly in a death and the other one very fortunate survivor.

I love this place and will be back soon, I just need to put in my order for these amazing conditions again.

The remaining pylons of the old Port Willunga Jetty would have to be one of the most photographed iconic features of the greater Adelaide coastline.

‘Most photographed icon’ often translates into kitsch so I looked for a different perspective in those last rays of sunlight and found one.

You’d never even know there was once a jetty here except for those shadows of the past.

Indistinct shapes move among indistinct forms.

The large forms wobble, snap back; wobble, snap back; wobble, snap back. As if they are trying to escape some invisible force holding them in place. They have been trying a very, very long time.

The smaller forms wobble, drift; wobble, drift; wobble, drift. The force that brings them here is less obvious, more fluid but still there. A force as ancient as the stones themselves.

Stony Point in winter relives this dream year after year, decade after decade, perhaps century after century and possibly unaccountably longer.

No one knows how long the Giant Cuttlefish have been coming here.

Let the dream last.

More often than not when you want to capture an image of some particular critter they have other ideas. That’s how it usually is with Shaw’s Cowfish, (Arcana aurita).

I have countless images of cowfish where as get my camera into position they turn adding yet more backsides to my collection.

I was expecting things to go the same way again on my last Rapid Bay night dive. Just to rub it in this little guy joined me almost as soon as I got in the water.

I tried an initial few shots and was immediately rewarded with more backsides. At that early snub I lost patience and proceeded on my dive to the jetty’s T-section. Several times this little guy kept swimming in front of me and I refused to make even an attempt! On I went.

On reaching the T-section I turned on my red lights, started hunting for photo opportunities and discovered I’d been followed all the way to the end. This time the little cowfish was happy to swim in circles in front of my camera and I finally captured that cute little face.

I am glad she had more patience than I did.

I think Lady Beetles are my favourite of all the insects that inhabit my experience. For reasons I have never been about to fathom, every time a Lady Beetle flies into my world I smile and am happy.

For as long as I can remember I have been entertained and delighted by their clumsy antics. Often landing on and exploring the most absurd of things I have always been at the ready to rescue and repatriate them back out into the garden again at the slightest hist of distress.

Lilies too have a special place in my memory with their affinity for creeks and streams and their regal slenderness. Unlike the pretty flowers mum grew in her garden, these denizens of bracken fern spring watered gullies were mysterious, exotic and compelling to be near.

Here in a little Adelaide Hills creek where I was drawn by the lilies, I was delighted to capture two of my favourite things in the one moment.

A thing of childhood nightmares lies before me, mouth agape. Like the edge of a precipice I am drawn inexorably towards that perilous abyss beyond. Every fibre of my being screams ‘don’t’ while body inches forward regardless.

After all this Doughboy Scallop is only a few centimetres across and I want a really good close up shot!

Scallop’s are actually quite interesting critters in more ways than just a favourite menu choice. You’d never find one of these on your plate though as the Doughboy Scallop forsakes a mobile life on the sea floor and settles instead for a permanent niche amid the sponges and other benthic life. Once a permanent home is found this guy will never move again unless his home is wrenched away by storm or other trauma.

As for those amazing blue eyes. They are a marvel and what always draws me inexorably towards another image!

Sorry I did not cover my mouth, said the gurnard perch, but we have no mask wearing restrictions down here! That spray of particles in the water is not Covid but the chewy bits of my last morsel!

I watched this little guy for some time, curious he was not at all perturbed by my up and personal presence. After all I was at least a thousand times bigger and wielding mini Suns to boot!

Soon it became obvious. My lights attracted small swimming crustaceans, like insects swarming to light on a warm summer night. My little gurnard friend had suddenly found for himself a mobile food truck and was settling in for a feed.

After any decent sized morsel was sucked into that gaping pout, out spat a shower of debris! Bless you I said as I packed up my truck and moved on rather than put on a mask of my own.

The first public performance for any new band can be a nerve wrenching experience, or so I have been told, and told and told again during the lead up to last Sunday’s gig at Littlewood Agapanthus Farm.

Even for my amazingly talented wife, being her debut as lead singer, it took ‘anxious’ to a new level.

All those nerves however evaporated in an instant when these six accomplished musicians launched into the first song of their set and confidently introduced ‘Talk On Corners’ to us all.

For a solid 75 minutes they rocked and sang and entertained us. They got us tapping, they got us singing along and they might have even got some dancing, a fact I can neither confirm or deny.

Congratulations Sara Sizer, Nick Carroll, Jennifer Liston, Peter Franche, Christine Morphett and Robbie Lennox on an awesome debut performance.

Diving under the old Rapid Bay Jetty is often just like catching up with old friends, mostly good fun but sometimes leading to unexpected and beautiful surprises.

Normally divers avoid currents, the biggest risk being swept off a dive plan and getting lost. Diving with a reference like a reef line or jetty pylons can restore safety in even moderate currents although you have to work for it. So it was last Thursday evening as I entered the water and was quickly carried by the current from the new jetty to the old where I began my dive – and that’s when the magic started.

The water was alive with light! There was so much light I didn’t even have to turn on my torch. From the sea floor to the surface every jetty pylon was flashing with fairy sparkles. It was like walking one Christmas evening through a suburban street where all the houses were competing for Christmas-light bragging rights.

That supernatural underwater light show was produced by large quantities of bio-luminescent algae from the nutrient-rich gulf waters being swept out with the ebbing tide. As they jostled and swirled around pylons and other structures they sparkled with tiny outbursts of light.

As I swam under the jetty northward every object twinkled. Every pylon shimmered with flashes of mostly white mingled with yellows and the occasional reds. Streams of fairy dust swirled off the pylons and streamed in the current.

Even my own progress through the water was showered in this magic – specks of light erupted all around my camera, flowed up my arms and swirled around my mask before disappearing behind me.

This was the most amazing display of marine bio-luminescence I have ever experienced. What a pity I was only prepared for macro photography and could not capture the spectacle. So it was I arrived at the jetty’s T-section, reluctantly turned on my torch and banished the fairy lights into the darkness.

So back to macro photography and old friends, this nudibranch (Ceratosoma brevicaudatum), a Rapid Bay regular, appeared right on queue for our regular catch-up.

Wow, what an amazing evening. One I will never forget.

Anyone who as taken a flash photograph while it is snowing would know just how annoying those fuzzy white blurs of light can be.

It’s like the physical world is conspiring against you. You see your subject fine through the rain or snow yet in the captured image the main even is upstaged by a flurry of bright white fuzzies, back-scatter.

Back-scatter is a very real problem for those of us who dive in turbid water. It is caused by the light from our flash or strobes hitting tiny particles in the water closer to us than to our subject. The result is usually white fuzzy mess.

There are techniques used to minimise this effect such as moving strobes or flashes well off to the side or far back behind the camera lens. At the end of the day however, removing back-scatter usually becomes a tedious post production activity. A necessary evil of underwater photographic post-production.

I have removed most of the back-scatter in this squid image leaving just enough to remind that dive conditions, especially for photography, are never perfect.

As beautiful as my last dive was I was a little disappointed that I was not able to find and photograph more critters.

What else could I photograph while on the last of my air? A selfie or something way more interesting? My dive watch!

So here it is buckled to an unsuspecting ascidian. Not so fishy.

And yes it really is just after midnight!

Well it was more like ‘boo’ than ‘bump’ as this rough rock crab (Nectocarcinus integrifrons) stood its ground.

I am not sure who was more surprised as I swam past a pylon to find this guy, claws reared, and that unmistakable ‘do you want a piece of me!’ look in its eyes.

I am sure I could have taken on the beast if I was feeling belligerent but there would be blood in the water, my blood and I was not looking to invite an even bigger sparring partner this time around.

So I dipped my mask and swam by with a nice wide birth. Perhaps next time.

The European Featherduster Worm (Sabella spallanzani) is an unwanted and feral guest in our South Australian waters. For the most part they are quite unattractive, living in silty conditions and lacking the vibrant rich orange fans of its native local cousin.

Anyone who has dived recently in Westlakes waterways would attest to the ugly mess they have made. Here however in the free flowing currents under Rapid Bay jetty they do not seem to have become too prolific and this one almost looks attractive in the night time strobe light.

Still I would rather this guest gone and our native featherduster in its place.

It has been way too long since I have been diving. What with work, the weather, too cold, too wet, reluctant dive buddies and any other number of reasons it just simply has not happened since July!

Last Thursday night I needed to travel south for non diving reasons and decided that since I was more than half way to one of South Australia’s best jetty dives, Rapid Bay, I’d pack my gear and invite my usual dive buddies for a mid week night dive.

It rained all day along with an unseasonable cold wind blowing from the South. Things were looking grim, … again.

To cut a very long story short I finally got wet again (fresh water first from the rain) and once again found myself amid the familiar pylons of the old Rapid Bay Jetty.

Despite the strong southerly winds this was one of the most gentle dives I’ve experienced here. The visibility was amazing, at least 10 meters, there was no current and the rain created beautiful reflections from the surface above in the torchlight.

Even with the gentle conditions there was not a lot to photograph. My highlight of the evening was a chance encounter with an old friend Doriopsilla carneola who I’ve not seen in more than six years. We exchanged hellos, posed for photographs and then went on our ways.

The moral of this story is there is never really an excuse not to go diving! Even if it means a very, very late night!

Cuttle’s Last Stand

Impressive as his pose may be there is not much fight or life left in this big male cuttlefish.

Countless fights have fought for the reward of an intimate encounter. He’s still in one piece so there is a very good chance his progeny and genetic line will live on. That’s all that matters in the life of the giant cuttlefish who have congregated this winter at Stony Point near Whyalla.

Perhaps he will enter the fray one more time, perhaps he will become prey to some larger predator.

Regardless, this is probably Cuttle’s last stand.

Framed by curtains of rain, bathed in sunset gold, the sun peeks below the dark clouds of the receding winter.

Not since I was a child do I remember rain like this season has brought.

As if the curtains of winter were finally drawn back, this weekend was the first in weeks the rain has not taken centre stage making our plans its own.

The rain will be back soon but for now I am enjoying the sunshine of the coming spring.

As we sat out watching the sun set on the distant Flinders Ranges and bathing the Waukaringa Hotel ruins in amber light, we were not alone.

Along side us, sunbaking on her own piece of ruin, this Bearded Dragon cared not for the visual beauty of the outback, only the last rays of sun keeping her warm.

Bathing in the emerald green shallows of Stony Point this sealion, belly full of cuttlefish, is probably the most content creature on earth.

To us the Whyalla cuttlefish season is an extraordinary opportunity to swim with, observe, and simply be with one of our most amazing sea critters. To sealions, it’s a gastronomical smorgasbord with one item on the menu.

For now, belly full, I’d wager she is dreaming of more tomorrow.
