As Pete49 says - check out Choona Chaser's posts - he had some great success with his yak fishing up there (his posts are here: search.php?author_id=27563&sr=posts
I believe the big lizards are more aggressive in the wet/stormy season (which should almost be over just now ....) .... but make sure you play safe - maybe message CC for suggestions??
Some fishing tips from another forum: On a run in tide you can fish for milkfish just on the outside of the no fish zone out the front of Doctors Gully fish feeding joint. Use bread and make a floating bread trail that will run down into the no fish zone. This place is full of milk fish.
Use 15lb leader and a thin but strong size 4 hook. We were bending straight Gammy bait holders every time.... Fish a unweighted bread bait sqaushing one end of the bread onto hook and leaving the other end normal. This will keep the bead afloat and the sqaushy bit will hold the hook in the bread. Just drift your baits back into the trail and wait.
We found normal cheap white slice is best for burley and buy 2 loaves of uncut white for bait. Stays on hook heaps better than sliced to.
We got fish to 6kgs and saw fish over 10. I have never seen a spooling so quick and it even got my Branzino C/fibre spool hot to touch after the first run. Best estuary fish I have caught so far for sure!
Check out the main wharf at night. The restaurant at the start has lights in the water until about 10 o'clock. You can see the monsters busting up after the baitfish. I hooked a massive Queenie there that ran me for ever, rubbed me around some pylons , only to bust off about 10 metres away. I hooked other things that I didnt get a chance to see, as I was either bitten off or busted off as soon as it hit the water.
The local guys use the Squidgy slick-rigs in white, or the "glow-in-the-dark" metal slice. I found the slick-rigs only caught Long Toms, nothing else would look at them, though they give a really great fight.
The slices worked best at night, but you need to use at least 40lb mono because the mothers there are big, mean, and fight dirty!
Can't wait to see you hooked up to a big barra!! Also, don't forget those massive Milkfish (you can catch them off the rocks opposite the place where they feed them .....http://aquascene.com.au/fish-feeding/fi ... ing-times/
Spots for Milkfish (take 6 loaves of white bread with you):East point, Doctors Gully, larrakeya,Cullen bay rock walls- Berley with bread and wait for em to show up, use 2/0 hooks and 15-30lb mono for trace and make sure your reel has plenty of line and a good drag,
