South heads @moruya has shelly beach very sheltered good parking, good ameneties, proper toilets, showers and free BBQs.
If 4x4 is somthing you guys want to do, head up deua river road towards Araluen and turn in at Dry Creek Nice day spot ... cross the river and head up Merricumbeen firetrail, once a the top there is a trig station and excellent photo ops, from here you can go into Bendethera - again decent facilities if the vandals have not been through. This is a decent run up Merricumbeen fire trail, once on dampier road its a doddle. NO trailers, you will get stuck.
Other options are from moruya head out Nth heads road to the airport and continue to Broulee, there is a tidal creek right where tomikin starts (candalagen Creek) again good facilites safe kiddies swimming spot... keep on going up the coast to Batemans Bay, turn in to burrawarra point and gurilla bay nice walks good photo ops. Swimming at gurilla Bay unsure of facilities maybe toilets.
Keep exploring up to batemans bay, then durras.
If you head south out of Moruya, dont go to tuross ... its a shithole full of angry old ex politicians (when I lived there its nickname was gods waiting room).
Bodalla cheese factory may still be open, then turn in at Dalmeany and do the coast road round to Narooma .... go to the golf club for lunch ... not for the food which is OK but the view is magnificent.
Then as Tony says Central Tilba, then down the coast to Bermigui ...MUST get fish from the co-op take away ..... massive shark jaws inside. Superb fish and chips.
So Durras is about 45km north of Moruya and Bermi is about 80km south PLENTY to see and do.
I cant advise on local fishing but in moruya there is a tackle shop that is very helpful to tourists .... The local airport has joyrides that were cheap for a 30 min aerial tour.
Dont swim at the rocks on north heads, many large blue ringed occys there.
