Go for an HID canister if youve got the bucks. You wont be disappointed. If your keen for a second dive go check out Manly Wharf. It can only be done when the ferries arent running and your already out there. Im guessing you would be doing it with Yves on Mindarie so it might be a bit of a drive from Rose Bay to Manly But thats all part of the adventure. Always kick on the next morning with an early one around Shelly Beach as well.
