Anyone wondering what its like up there - check the telegraph cove link in my sig - there are pics from this and last year.
Have to say - I've learned a lot about taking pics underwater since then! Might have to revisit some of those images - maybe just get new ones next year.
Anyway - a couple of videos

they are largish - you may want to pause them after they start to let themload.
