Caught hundreds of Yellowfin and never seen any worms or other stuff in them, Leatherjackets however, yeeew, never eat them ever, I have seen worm looking things in Bream, supposedly harmless and OK to eat.

Damn that’s a shame, never seen a yellow fin with flesh like that.
A few Jew I have caught out from the tweed have worms but even then the flesh doesn’t look like that.
How did you find the Brunswick bar?

Not to bad mate, bit scetchy on the way in nearly low tide and heaps short period swell. Wouldn't like to hit it any bigger than 3ft swell though. Pretty shallow.

That looks like a Kudoa infection - what you are seeing is large numbers of small "pseudocysts" throughout the flesh represent plasmodia, each containing many thousands of tiny parasite spores. This sort of infection is typical of certain species of Kudoa parasites, a group of small protozoa like fish parasites which are actually parasitic cnidarians (i.e. related to jellyfish). I certainly would not recommend eating fillets that look like this as some Kudoa spp. when cooked exude enzymes that liquefy the flesh, making it tasty and boitter/tasteless, while other species can be toxic and cause illness.
