there's kingies at montague island but its a bit hit and miss these days, and you have to cross the bar. Other option is to launch from bermi, bit further to reach the island but no bar to cross. If you launch from Bermi, we have picked up some stripeys and albies between the six and twelve mile reefs (you might need offshore safety stuff like epirb...) if you find its too far out then there are a few reefs like the steps etc closer to shore, just drop by bermi bait and tackle and ask Scott for the good oil.
hope this helps.
cheers
