We'd suggest if everyone that wants to sell stuff do it on the Saturday morning it might be more attractive to anyone in range. This also ensures it doesn't conflict with the Boonah Country Markets held on the 2nd and 4th Sunday of the month 20km East of the site.
C.A.W. is only suggesting we all camp together and takes no responsibility for property, insurance or personal liability. All selling at your own risk and using your own insurance.
