Is this too early? Yes it is, but necessary.
We will be staying at Kalgan River Caravan Park, but are unable to book out the park exclusively. So we need to start getting members to contact the park and start making their bookings now. You only need to pay a deposit on booking and the rest when you arrive, so ring up and make bookings for as many sites as you need. State you are part of the WA 4WDA and are booking for the gathering weekend.
Powered sites are limited, but there will be plenty of space for unpowered and there are also cabins available.
