By the reading i have come across on other forums, I would say Illegal

Cut out of another forum posting legal and illegal bike riding areas

Logan Village Pine Forest-Illegal
Great riding, Can get dusty if it hasn't rained for a couple of weeks/months. Lots of traffic, be careful of 4x4's & other bikes, keep to the left where possible & slowing down for an intersection is a must!
Police will blitz the area every now & then, usually giving out warnings(depending on attitude from yourself & other riders). I believe a rider has been killed in an accident with a 4x4 here.
Most people enter via the 'power lines' Which is off Waterford-Tambourine Road, just past Camp Cable Road.
