Anyone heard of the (public) land adjoining a Rural Fire Service (NSW, QLD, ..) building not allowing parking, because it's a Surprise Helipad?

I had my van parked at one last night, and in the morning this richcunt Queenslander Caravaner told me off. (Fuck Him. I parked where I did so I wasn't putting up with his diesel heater all night.) There was no signage mentioning it as an airfield, nor was there an active fire event.
