I'm a PADI advanced cert diver in Sydney Australia for business, didn't
bring any gear since I knew I couldn't get up to the GBR due to
logistical info. Now I'll be staying over the next weekend (10/7 10/8)
and I'd like to get a dive in. I know Sydney isn't by any means the
GBR, but just to get wet and see some local underwater sights.

Can anyone recommend a dive operation here in Sydney? I see one here
that seems to do shore dives  ("Let's Go Diving Sydney") and another in
Manly, about 6 miles away ("Dive Centre Manly"). I hate doing this
stuff blind, it's almost gotten me hurt in other countries so I'd
appreciate any feedback. Need to rent gear, of course. Thanks!
