Mackerel Tuna

Euthynnus affinis

Known as “the little tuna”, this pelagic fish belongs to the family of fish that includes mackerels, tunas and bonitos. In Sydney, you’ll find them close to shore in large migratory schools.

The Mackerel Tuna has a noticeable dark-striped pattern on its back with a few dark spots. You’ll see them in schools mixing with other fish – adding to spectacular background on our dives.

I had an awesome couple of dives on the Ex-HMAS Adelaide for my 100th dive. It was an amazing experience thanks to Jason’s excellent boat and service, his detailed briefing really helped me navigate the ship wreck.

I’ve chartered Sydney Dive Charters for my company’s annual Christmas party and we had a great time, the boat is great and Jason really went out of his way to accommodate our needs. I will definitely be back on board this year!

“I’ve been diving with Jason aboard Sydney Dive Charters dive boat for nearly 3 years now and I keep coming back. I’ve had the pleasure of exploring and enjoying some of the best technical wrecks in the Sydney Region.  The boat makes for comfortable, easy diving – which when coupled with Jason’s local knowledge provides a complete service. There is nothing better than diving on a boat when you know the skipper is first and foremost a diver himself”
