I've been searching for a trip report on this one given I haven't recced it beforehand and finally found one from Nov last year. Credit to "marc_mmg":
Hi Guys, just wanted to post an update on the Hunter Range track. I took my family up this track yesterday in our NM Pajero, and it's a bloody long run.
We went from the Windsor end, turned in at the Putty turn off (about 90 clicks from Windsor up the Putty Rd) The track condition varied from 60-70 km/hr dirt track (fire roads in the Park) to 5 km/hr terrain that almost shook the old girl apart! Because of the rougher terrain the total trip took 10 hours (from Kellyville - full track - back to Kellyville) and this only included stopping for 20 minutes for morning tea ( to fuel up the rug rats) and then about 30 minutes break for lunch at the old Drovers huts. This run is listed in the 4wd treks Close to Sydney book for anyone wanting to take it on. It is by no means a difficult track (in fact a rental Commodore could do 90% of it - rentals make the best off roaders!) The lat/long points are good (although my VDO MS5000 was showing slightly different readings than listed but close enough to know we were still ok) but my one warning is to stick to exactly what they say. There are a lot of new tracks now as there is a lot of logging going on in there, and I made the mistake of taking the right fork at a Y junction as it looked more used and a better track - opps - it took us deep into the scrub to a dead end where there was a heap of logging equipment parked up. 14 kms the wrong way at about 14 kms/hr, so that added some time to the trip!
The old drovers sheds are a good spot to have lunch etc (and they have just recently put a beaut new long drop in there for the etc!) The tracks are in overall good condition, but as you head away from the drovers sheds (heading Northish) you go onto sections of private property and thats were the track becomes rough as guts! As I said, not challenging but rough enough to bring the pace back to walking! We only passed one other vehicle all day heading in the opposite direction - sorry about the dust!
Overall a good run, but it is long and time consuming if you want to preserve your suspension and tyres by going at a slower pace (a lot of rocks abaout the size of tennis balls and bigger which are great at shredding Pirellis!)
So sounds like it really will be easy but could be a long day, especially for those already travelling a fair way to the start. I'll make sure I bring the compressor for this one so I can drop the tyre pressures for a bit more comfort.
