Karl Shreeves and I took the opportunity to make a trimix dive with some of the local tech gurus at a wreck site off Sydney today. 46 metres, with 20 minutes bottom time and just under an hour total runtime. A good dive on the Coolooli with a lot of marine life about; even a dozing shark. My thanks to Richard Nicholls and Liam Allen for showing me around.
