Check what tracks are seasonally closed; there are quite a few in Toolangi, & as others have said Rocky Tk is not one to take inexperienced 4wders up. As Aeroplane is no longer a seasonal closure, unless you have 33's, expect to do a fair bit of winching if it is wet & even after the little rain we have had over the last week or so, it will be wet.
There are plenty of other tracks other than the well known ones that will keep you on your toes & would suggest you should give the likes of Rocky & Aeroplane a miss, especially during winter. If you havent got one, get yourself a Rooftops map of the area.
