What mysteries lurk under the surface of Sydney Harbour? That's what Google wants to find out by mapping Sydney's murky depths with a raft of gadgets, tablets and underwater cameras for a new Street View project.
The team, working with Google and the Sydney Institute of Marine Science will use a bunch of underwater cameras controlled by waterproof tablets.
It's a mammoth job, and one that will take around eight months to complete. The results will be shown off at a conference being held in Sydney in November.
So far, some of the weirder things Google's team has found so far include trolleys, a bathtub and a whole lot of rubbish. Seriously, Sydney: stop it.
I wonder if they can find the ships that went down in the attack on Sydney Harbour...
