It is about 6km off the highway and righ onto a dirt tarck(there is signs everywhere) it is a nice and queit area, there is fishing in coochin crk and 4wding available around you... it is wounder full, you can see wildlife, there is a boat ramp, you most probably will need a 4wd unless it hasn't rained for a while but some of the road is gravel but does get dirt towards the end, 

To get there you turn right at Roys Rd (coming from brissy) and then follow the road up and you come amoung Coochin Rd, you keep going when you get to it and you turn right at the next dirt track, there should be signs there so you shouldn't get lost going there.
