Had done this dive 6 days prior on a calmer, sunny day... had 15m vis throughout the dive, and did not need a torch while going into the cave. also had the sharks in the same place on this dive.

This Dive:
Water was very soupy before entering. myself and my buddy are very comfortable in the water, and entered knowing conditions were not ideal. (DO NOT DO THIS DIVE IF YOU HAVE NEVER DONE IT BEFORE, OR IF SEAS ARE NOT DEAD FLAT).. seabreeze was reporting waves 4ft from the SSW when we dove.
after swimming out through the initial soup, we decended to 4~m of water, and continued out until the drop off to 16~m
swam through the the cave (rock over crack) and went in.
swam into cave, and almost straight back out - it was a little surgry, and as we were swimming to the haven wanted to save as much air as possible.
in the cave we had a grouper- i thought he was going to bite my gopro (would have it surrvived?) schools of bullseye, and yellowtail (I think they are yellowtail... happy to be correted?)

ran into the 3 grey nurse sharks about 5minutes after the cave, this is the exact same place I saw them 6 days prior (saw 2 at this place, and a 3rd in the haven.... all 3 sharks looks very similar to previous dives)....

BIG APOLOGIES for my camera work with the grey nurse sharks... I have 3 excuses...
first being, this was my first day diving using the selfie stick, as such, the entire dive the camera was pointed way to low (lots of footage was cut).
second: I had the gopro set as a narrow FOV... I wanted this so when I videod smaller flish they didnt look tiny, this meant I couldnt just point and hope, as you do most of the time with a gopro
third: vis was pretty poor. when I saw the sharks, I turned the camera on straight away, afterwards I moved into a safer location (against the rock wall) then identify the sharks as nurse sharks.. (when I see a decent sized shark I think 1. turning on video 2.saftey 3. what the video sees). because of this and the gopro being angle to low, they were massively out of frame.

afterwards did the swim around into the haven... staying in 5-10m of water most of the way, and keeping the rock wall on our left.
had the second grouper at the haven.
