I replied in the camping thread

I also want to point out that I have a station wagon, my friend has a sedan. We usually go camping together & have enough room.
Her partner also has a 4wd, so we have that as well (if he comes & depending where we're going) & we all pile in when my car goes as far as it can. Beach camping etc. But there are still plenty of places to go in a regular car.

Free sites usually have no facilities. Sometimes there'll be composting/long drop toilets, maybe even a cold shower in beach areas, but don't expect it.

Always carry garbage bags & prepare to take your rubbish with you at free sites. They don't usually have bins either. There are national park sites though. You might pay a few $$ for access, but they usually have toilets & bins. Maybe $5-$10. No animals allowed.

Best little quote my kids have learned with bush camping - take only photos, leave only footprints
