I can't say I have seen or heard of to many people have consistent success inside catching snapper. If they are they probably aren't sharing it.
I'd say anchor up near reefy territory pretty close to the heads, berley with pillie cubes. I have caught the odd one near the oil wharf this time of year on the run out tide. I'd guess Watts reef, mol point, Bare island are worth a shot.
Why your waiting your likely to get some Trevor's show up. An underrated table fish IMHO.
