The Adelaide Exhibition and Convention Centre has got a few parts that don't conform to 90 degree traditions.

Where panels become planes, joins become lines and light plays over geometries you could be forgiven for thinking you were in school rather than walking down North Terrace.

The Giant's Causeway?

Of course not but these hexagonal interlocking concrete columns remind me of the basalt columns of the Giant's Causeway on the west coast of Ulster, Northern Ireland.

I love seeing architecture with strong ties to geological and natural forms, even if unintended. Mostly these are large civic or commercial structures which have the scale to explore form.

Personal dwellings though seem stuck in the recent past unable to break from mostly unattractive traditions.

It's obviously not moonlight illuminating this underwater vision but I could not help but feel as if it was the way the light draped over dragon and kelp.

This Leafy Seadragon captured at The Bluff, Victor Harbor, was just one of many we photographed in one of the best days here I have had all year.

Is this outside looking in?

Is this inside looking out?

Is this outside looking outside from the inside?

Is this inside looking inside from the outside?

Or all of the above?

A solitary gull drifts back and forth in the late afternoon, its gaze intent on the breaking surf beneath it.

If it were human it might be searching for unusual shells discarded by their deceased owners to add to a growing collection.

If it were a flying fish it might be searching for a safe place to dive back under the waves again.

The truth more likely is that the prize will be some unsuspecting critter about to become the evening's dinner.

Who's following who here I wonder as this school of Zebra Fish (Girella zebra) cruise through the pylons of Rapid Bay Jetty.

These fish are mostly juveniles but near the front of the school there are a few adults who seem to have things in hand leading the young ones from pylon to pylon.

On some pylons they feed and make a real mess. On other pylons they seem to just want to rub themselves up and down.

Then they are off following each other again.

It's all about the angle when searching for dragons.

Leafy Seadragons are masters of camouflage, blending into kelp or any of the other brown algaes they associate themselves with. You could be looking right at one from the side or from above and not even realise it. Get below one, however, where there is nothing but dragon and blue sky above, and that amazing outline is brought into dramatic relief.

Another magical dive at The Bluff on a day that provided all the angles.

This cave dwelling sea star caught my attention by being perfectly oriented, in the middle of a large limestone outcrop and being so contrasted to its surrounds.

When many divers think of cave diving they imagine fresh water, sink holes, minimal life, impossible depths and meticulous diving logistics.

When I think of cave diving I imagine beautiful colours, strong surging currents, prolific life, corals, ascidians, sponges and sea stars. It's as if we are on different planets.

This small cave on the ocean side of Chinaman's Hat Island is just one of the many caves, ledges and swim-throughs that make this dive one of the most spectacular accessible shore dives of the Southern York Peninsula.

Diving here is the perfect example of the rugged oceanic South Australian limestone coastline. Big swells or high seas make many locations like Chinaman's Hat too hard or too dangerous. On a good day (and even then you have to work for it with an initial swim out to the island) it is spectacular. On a bad day leave the gear in the car and grab a surfboard instead.

Yes I like caves; salty ones full of cave dwellers.

It's getting too hot now in the Flinders Ranges for most daytime activities so I probably will not be heading up there again for a while now.

This sunrise over Rawnsley Station is from a trip a few months ago when it was a little cooler. As I sat up here watching the sunrise a warm glow swept across the valley floor before the sun finally appeared at the top of the bluff bringing sunlight to this ridge top.

Well it's the first day of our southern summer and the ducks will rejoice because it may as well be winter again.

It's windy, rainy, cold and generally uninviting to go diving. I am hoping the weather will quickly recover so we can get back in the water again.

In the mean time this Pacific Black duck (Anas superciliosa) thinks all is well with the world as it waddles up the beach basked in the golden glow of sunset.

We are about to enter summer here in Adelaide, in the the driest state on the driest continent (according to popular folklore).

During winter I would have been washed away attempting to stand here in the outflow of the River Torrens. Today this parched mud floodway suggests just how dry our summer will be.

There will still be water in the River Torrens around the city and in deep pools downstream, but precious little will find its way to the ocean for the next six months.

Standing here feels strange. Like standing in the middle of a silent freeway once busy with cars and trucks ready to run me down. I like the strangeness. I like the separation from a time before and a time after which would make this image impossible.

Some time well into next year it will flow here again but for now it is the ex-stream of the River Torrens.

Dive the shallows of the old Rapid Bay Jetty at the moment and you can expect to be stalked.

This school of Zebra Fish (Girella zebra) started following me around as I searched the general area for other critters. Soon I was so caught up in their antics and carry on that they had me for the rest of my dive.

I'd follow them and then they would follow me. At times I found myself in the middle of the school and then they would break away out into open water only to loop around in big circle to come up behind me again.

Every dive at Rapid Bay is special and this dive the Zebra Fish made it magical.

The wonderful thing about sunsets is we get a brand new and completely unique one every single day.

The sad thing about sunsets is you will never see another one just like the one you saw tonight.

So many times I find myself watching an amazing sunset unfold and not being able to photograph it. Maybe I might have even lamented to a nearby sympathetic ear on the lost moment.

Almost without a second thought the response comes back, "there will always be another". Perhaps if they had lingered on that thought a moment longer they would have realised that there never will be.

I am not sure which location I prefer for Leafy Seadragons, The Bluff or Rapid Bay.

Rapid Bay has an incredible diversity of sea life and never disappoints even if I do not see the critters I have come to photograph. It is a safe bet for a great dive even when the conditions are not so good.

The Bluff on the other hand is rough, has poor visibility, is exposed to southern swells but I never fail to find Leafys here. Even though this dive does not have the variety of life the Rapid Bay offers it has a rugged oceanic appeal that makes me come back time and time again for the Leafys of course but also for the great granite bombies, the thick kelp, seals, crays and of course the usual suspects (a technical term for local South Australian reef fishes).

This Leafy Seadragon (Phycodurus eques) is being swept back and forth through the kelp and around boulders but doesn't seem to mind at all. This is typical of their environment here and is what makes this dive so appealing.

The iridescent blue eyes of the Doughboy Scallop, Mimachlamys asperrima, are little optical marvels. They are in fact more like tiny Schmidt telescopes than conventional eyeballs.

The back surface of the scallop's eye is like a mirror which reflects the incoming light back towards the lens opening. The light sensitive cells of the retina are on the back of the lens and not the eyeball so they actually sense the reflected image back off the mirror.

As far as eyeballs go they are are quite rudimentary and not much more than a pin-hole lens. The internal mirror structure however gives the primitive eye a huge light gathering advantage important for dim lighting conditions, sufficient to detect the approach of predators in near darkness.

Despite their amazing biology, from my point those alluring blue eyes are just stunning.

This Leafy Seadragon headshot was taken during a recent daytime dive at Rapid Bay.

This is another example of extreme separation normally associated with a night shot but instead done through strong strobes and removal of the blue luminance.

I expect he'll be wearing dark sunglasses next time I return.

These yellowtail seemed so regimented into their 'march on by' that I could not help but imagine they had been given their marching orders.

Although this looks like a night shot it was actually created in full daylight by using a combination of bright strobe lighting to 'drown out the daylight' and then pulling back the blue luminescence in post production. The result is this striking black and silver contrast between fish and water.

March on by.

A few weeks ago I first noticed the behavior of a male toadifsh (Omegophora armilla) collecting objects and filling a discarded bucket with them. On this dive I found another toadfish behaving in a similar way but this time filling a large sponge.

I wonder if they have completed their collections yet?

What happens when they start to overflow?

Have either suitors attracted a mate yet?

This weekend I plan to go back and visit Toad Hall and see how both are fairing.

Imagine for a moment that going to heaven for a fish might have something to do with that strange sunlit world above?

Twenty years ago, 'up there', would have been teaming with amateur fishers angling for a piece of undersea action. From the fishes perspective the last place they might wish to go.

For years now Rapid Bay jetty has been slowing collapsing into the ocean. No one sets foot on its structure anymore. Sections of the Jetty are completely gone and no more fishing lines descend from above.

Where once were fishers there are now gulls and cormorants and of course fresh air.

For the fishes heaven will never be 'up there', only death.

Sepia apama, the Giant Cuttlefish, is the largest of the cuttlefish and a South Australian draw-card critter. Thousands of cuttlefish congregate to mate in the shallows at the top of Spencer Gulf each winter creating amazing opportunities for divers and snorkelers to observe their antics in only metres of water.

This guy however lives out in the seagrass near Rapid Bay jetty where there was evidence enough he was up to antics of his own.

I think I have enough moon images now for an independent collection but just because ... here's a new one.

Last night's waxing crescent is still mostly showing shadow but if you look really closely the almost hint of a full outline gives it a depth not perceived when the moon is full.

I may be looking up towards the light but that's of no use when it comes to lighting the way. I bring my own.

Conditions at Rapid Bay were sensational yet again with more schooling behavior under the 'Tee' than I have seen for a very long time.

As I arrive at the site I pulled up next a group of very happy divers who were laughing, whooping and exclaiming how exciting it was finally become certified open water divers.
I did not realise it then but later as I swam though forests of schooling scad, marveled at the visibility and was captivated by the dappled sunlight on the sand I realised just how special a dive those brand new divers just experienced.

I hope the conditions did not spoil them as South Australian diving ranges from sublime to ugly depending on the day.

This one was particularly good!

A wonderful gathering of people at Coriole Winery enjoying the wine, the pizza, the fire, the ambiance, the food, the company and of course the poetry.

Poets Amy Bodossian, Jennifer Liston, David Mortimer, Jan Owen and Jude Aquilina entertained us with verse, song, prose, rhyme and whit while the Coriole team kept the pizzas and wine coming.

Looking forward to the next one already.

This poor guy is suffering war wounds of love as he and many other suitors battle it out for the available girls.

There seems to be a lot of cuttlefish activity at the moment with both males and females engaging in all sorts of games.

If you look closely here you will notice translucent lumps all over his body where other males have taken chunks. The translucent colour is due to the lack of chromatophores in the wounded area.

He's fairing pretty well I'd say and will be up for a lot more before the season is over.

The Majid Spider Crab, (Leptomithrax gaimadii), is commonly seen critter in South Australian coastal waters.

Equally at home in the sea grass, the rubble or on the jetty pylons, most of the time we see them as solitary scavengers or as mating pairs when the time is right.

There is however a certain time of the year when they come into the shallows in their thousands as walking wall of spider crabs two or three deep and tens of meters wide.

Just not today.

Most divers at Rapid Bay perform the usual ritual of crossing the sand from the new jetty to the old before really starting to pay attention to their surroundings.

Granted, the old jetty is certainly the draw card here but take the time instead to head off in a different direction, over the seagrass beds and it is an entirely different experience.

The seagrass is home to all sorts of interesting critters most of which you have to look carefully for as they hide among the grasses but not the leatherjackets.

Just like people, there are fish which collect things to show off.

I first spotted this Ringed Toadfish (Omegophora armilla) guarding a large white fishing bucket resting on the sand near Rapid Bay jetty. Wondering what was so interesting about the contents of the bucket I swam over to take closer look.

Initially the toadfish swam away but not very far and then tried to swim behind me and back to his bucket again. I backed off a little, settled down on the sand and waited.

He soon came back, inspected the contents of his bucket and then swam over to a small broken chunk of coral nearby. After examining it for a moment he proceeded to pick it up in his mouth and swim back to the bucket again where he dropped it in on top of the rubble already there. It was nearly three quarters full and I can only guess that he must have been responsible for filling up that bucket right from the beginning.

A fellow diver suggested it was some form of mating behavior as he had seen other toadfish trying to fill more natural objects such as sponges with rubble such as shells and grit and broken coral.

With his big white bucket filled with rubble this guy is obviously out to prove that size really does matter.

Rapid Bay did not disappoint us this weekend with 10m visibility, minimal currents, warm weather and even the water is not so cold anymore.

Hanging around the t-section of the old jetty we discovered a huge school of Yellowtail Scad (Trachurus novaezelandiae). Initially they were timid but after a while they became used to us, allowed us to swim through them as they parted only to reformed behind us.

Another beautiful diving experience.

Another look on the amazing Eta Carinae Nebula to be seen in our southern night sky.

This fabulous structure can be seen in one of the most visibly dense parts of the Milky Way. There are 10s of thousands of stars visible here creating patterns of textured starlight, seemingly empty voids and the stunning Eta Carinae Nebula 10,000 light years away.

Too focused on his own subject to notice he was the subject of mine.
