Good for you.
We love camping and have bought a second hand CUB camper that has a small 12ft punt on top and a 8hp motor attached to the camper tow bar, next to the gas bottles.
Can offer no advice on your area.
Good eskies.
Always use as much block ice as you can.
If you can afford it get a fridge freezer, a small generator (incorporate solar charging if you can) small chain saw, axe, shovel (you never know), recovery equipment in case you get bogged, including fuses for you car, roll of strong tape, some wire (you never know)
Don’t forget the toilet paper and rubbish bags and insect repellent and stubbie holder and chair!
Always good to have a few extra tarps.
Obviously heaps more….
And importantly, “Let someone know before you go”
