Don't want to push my luck

yet still wanted to ask if there are any particular ones you would recommend.
Hi,
I’m no expert as have only been once, but we did a liveaboard with the aggressor and stayed 2 days either side of that. We went to the Darwin research centre which is really worth going to.
We also did 3 days of land based diving and it was incredible. Had a small school of hammerheads circling us at Gordon rocks for the majority of the dive. Also had a school of eagle rays pass a school of hammers at north Seymour. As well as a pass from an endless school of mobulas.
( I think that’s the site but it was years ago and I don’t have my logbook to hand)
Either way if you have any time to extend your trip I would definitely recommend it.
