Flinders... not really an ocean view, but at least access to the camping ground is easy as is access to shops, water etc
Main beach is tops, you just need to be set up for the sand and that means lowering the tyre pressures on 4WD and trailer and drive sensible to the conditions, remember momentum is your friend
As for the access points, some of the chutes you would not try, but there's plenty that are quite OK and once you are up just a matter of pick a spot that suits.
I can't say which because often they will change but, there's always a spot somewhere
When you book you are given a mud map, there's one spot about half way down the camping zone, the insode track disappears into the swamp
I have a standard 90 seried Prado and meduim CT (about 650kg), don't have much drama
the only thing with camping on main beach is access to drinking water, closest drinking water is at Pt Lookout, which has it's attractions, namely coffee and ice cream.
but water for washing can be had from the pools in the 18 mile swamp, not as far to go
if you can make it you'll be guaranted an ocean view but be ready if the southeaster blows up, I'd carry extra poles and ropes and not be open to that direction
PM me if you would like some extra info about it
