If you are looking for bream on the jetties, try Henley or Grange. Always heaps of bigger ones under the jetty and swimming around the pylons in the shallows. If your lucky you might get to see the dolphins come in and chase the bream around the pylons....bugger me they can move fast...incredible to watch! Same time you can catch yellowfin, same running sinker rig. They will take worms no probs. Otherwise, yeah West Lakes and I have caught quite a few bigger bream at Tennyson too over the years.
I went for a walk tonight just after sunset just to watch all the rakers....taking any size crabs as usual! But I did see out past the second sand bar where I was walking, 2 of, over a meter long Mulloway just cruising along. I once saw a monster mulloway in the shallows at Henley jetty just chasing bait fish.
Good luck on your mission lol!
