Struth Bicyclecamper, are there really CP who knock back accredited assistance animals ? It's been a legal requirement they are acceptable for decades now.
As a couple who live in our van 365, and stay in caravan parks the majority of the time.
It's very simple daily fees under $30 with a stay 7 pay 6 bonus, reasonable showers and toilets, angled parking preferable, separate section for pet owners.
Worth considering a single traveller rate about 20-30% off.
Consider separating sites with some vegetation like riverside CP at Cunnamulla and gunna go CP near Proserpine.
And of course Power & Water.
Dabbler, nearly all the c/van parks, we have been to, that don't take pets, will not allow is to camp there, even with the paperwork on hand showing discrimination is not allowed. We just freecamp virtually everywhere now.
