There's a boat load off off road locations in the back of total off road magazine every month, they call it 4x4 Playday Directory, all with addresses websites n phone numbers, days they are on, amenities etc etc mags not a bad read either, i been to most places up north all pretty good, some better than others but by far the worst place and worst VFM in terms of acreage per pound lol was Hill n Ditch a dissused SANDSTONE quarry with alot of water, only a tiny place and sand+water+engine didnt go well needed new starter and alternator after my visit there wasnt very challenging either.
