Northern Arch

January 23, 2022

Headed out to Poor Knights Islands and time to gear up the liveaboard boat for the trip.

Gearing up the Sun Spy

On the way there we got very lucky and a pod of dolphins followed us for a while. One juvenile dolphin was feeling particularly playful and kept pace with the boat.


Our first stop was Northern Arch. The visibility was excellent, the water was blue, there wasn't much current, and there was plenty of fish at play including numerous Kingfish.


The dive through the arch was nice and relaxed.

We got lucky and also saw some sharks there too! One of the other divers was signalling shark and I managed to get a video just before it swam off.

Unfortunately, I was so intent on capturing the shark I didn't noticed my Mares EOS 20RZ dive torch had managed to wiggle its way out of the pocket on my wetsuit. At least my buddy saw it happen and signalled to me that my torch had found its way to the bottom of Northern Arch. The max depth on the site is 40 metres so that ruled out me or my buddy going down to get it. Not great.

When I told the crew (of two) back on board the boat, they were gracious enough to say that we would dive Northern Arch again the next day. Then the dive instructor on the crew who was certified to go below 30 metres would have a look for it. A very kind thing to do for such a boneheaded mistake.
