Hi Dan,
I travel from Goulburn to Jervis Bay which is a couple of hours drive. The boat ramp at Callala Bay is brilliant. It has good parking, a cleaning and boat wash bay. It is well lit. There is heaps of holidal accommodation and also a caravan park in the area. As for the fishing there is plenty of squid to be caught, yellowtail and slimies.
I use a combo of striped tuna, bonito and pilchards for bait. You can catch just about anything in the bay. My last trip I caught snapper and mowong, port jackson sharks and just about everything else you can imagine. I use a combo of paternoster, floats, running rinker rigs and get plenty of hits on all of them.
I hope this helps.
Happy fishing
Shane
