You cannot drive 4WD on any of the coast beaches - but pick a beach anywhere between Broken Bay and Swansea there are fish- this time of Year Whiting, big Bream and Salmon with the odd taylor mixed in. The odd Jew are caught around Broken Bay esp after a good downpour of rain, otherwise nth Entrance is the go for Jews ATM.
Most beaches are still crowded esp on weekends so pick your times to go, I fish the run-in tide and prefer it around where I fish (Broken bay).
More towards Winter the 'ting really fire up and more Salmon + big Taylor and Jews coming in close to feed on the mullet run.
FYI- Live bait is best on the beaches but fresh local mullet/squid/yakkas and slimeys will all work on most species. Beach worms and tube worms are the go for the 'ting and bream ATM.
Good luck mate
