I loved the days(70's - 90's) , when you could rock up to a National Park, just pay your money into the envelope of $5.00, it usually had a toilet, maybe a cold shower, waste bins, that were emptied, firewood, clean area, and quiet. Could stay as long as you wanted, just keep putting the money in the slot. Now that is gone, and plus you are not allowed to smoke in a park( am a smoker), can at the most only book for a week. Must do it online, so if you are out there, and have no signal, you are s..t out of luck, to stay on, or you may be just driving or riding as is in my case most of the time, and come across a park, you just cannot rock on in spontaneously anymore. You never see a ranger there, and no you must take your rubbish with you, including your toilet waste if you have one, for the greedy fee of $37.50 per night. Their is a park in our area that charges $27.50 per night, for absolutely nothing supplied, it is being closed, as it is not being used at all. It will still be a park, you just wont be able to go there. NSW National Parks Service, are raising their prices yearly, eventually, people , may only do day visits, and just not stay overnight due to costs. We do not attend/stay at  parks anymore, and have not done since 2011. We stealth camp now, and in some really beautiful areas, and free camp in other open areas. This is what we will be doing indefinitely. We are pensioners, and cannot afford to do different.
