Longreach Tourist Park, Qld
Located just near the Qantas Museum and Stockmans hall of fame it is a very large park that can hold over 300 vans and does around 3-4 times a year.
It was a little quiet whilst I was there with no one stopping next to me for a few of the days.
It is all gravel as it is just not possible to grow grass across a park that large but the gravel is well maintained and dust suppression activities do their best.
Unfortunately many of the drivers even after specifically being asked by reception to not speed and good signage are doing 20+ past the pool where there are often kids.
The bathrooms are large and clean and easy to access and many of the tours will do pick ups from this location.
