Hi all!
This is a bit of a long shot, but i went for a walk at Northbrook Gorge at D’Aguilar NP and my waterproof camera detached from the lanyard/bag and dropped into the water.
I believe it would have been around the first lot of deeper pools.
If anyone finds a blue nikon waterproof camera washed up during their visit here, please comment back on this thread. I will repay you with a meal and a drink if you find it!
