Father's Day - underwater

This weekend Matt and I went on a father-son diving weekend down to Bateman's Bay to celebrate Father's Day.

We drove down on Saturday afternoon, and had a couple of dives planned for Sunday.  It was a good drive, and when we checked into the motel they upgraded us to a better room - so we felt it was going to be a great weekend.

The wind was starting to pick up when the boat left the Bay, and they had to change the dive destination because of the big swell to a more sheltered spot off a place called Black Rock - a small volcanic outcrop about 20 minutes out to sea.


It was chance for Matt to practice his photography as well.



Once we were underwater it was a lot more peaceful that on the surface.  There are a lot of things to see such as the plants below.  And even the acid-yellow coral growing on the rock.






We were also surrounded by big blue groupers.  They weren't the slightest bit worried about us - they were only curious and would come right up to you.  Sometimes it was downright scary to look to one side and suddenly see one of the just floating next to you.



As you can probably see, under the water everything looks a blue/green/grey colour.  This is because the water absorbs the red component of the light.  The following 2 photos show you the difference when you use a flash.  Because there is no red in the light spectrum under the water, a lot of creatures use red to camouflage themselves.

Here are some other underwater flora and fauna.  Fabulous colours as you can see.



Here is an interesting looking fellow.  I thought he was going to attack me for a minute.


All too soon our dives were over, so it was time to drift up to the surface..
