i am not the most successful when it comes to snapper, but i have found that anchoring off a patch of reef and burleying up aorund sunrise or sunset has worked best for me. stacks of areas just inside the 3 mile where you could anchor up, just not anywhere near where it breaks.

usually will at leats get some skippy, and i leave a unweighted mulie floating out the back in case the snapper swim by.

good luck

The back of the 5 fathom bank early morning or late arvo would be a good place to start. Just be aware of the snapper ban that is on at the moment inside Cockburn, Warnbro sound and surrounding areas. If your bringing snapper back through the banned areas make sure you dont stop anywhere inside the ban areas and have the track viewable on your GPS to show fisheries

 Any particular ground I should be looking for 

i usually find a bommie/rock, throw in the pick, and aim let out enough rope to be fishing just off the edge, usually just onto sand or broken bottom. fish a bottom rig, and have the floater out back.

keep a regular trail of burley going. i find the schools tend to intermittently swim past, keep the mulie floating out the back on low drag so it can run. most of the snapper i have caught have bene on the floater. i will fish the bottom for whatever else, then intermittently the reel will start screaming when the come by.

heading north or south of hillarys you will find a number of areas where there will be reeff surrounde dby sand. i usually fish in about 15m, and anchor on a bommie that comes up to about 12.

i personally havent had much luck catching any decent snapper outside of the reef in deeper water.

There's plenty out in 80 - 90 meters, just find a good bit of broken ground and go for it.

 Awesome guys much appreciated massive help
