Head 20m-or-so east of marked trig A9UM along the Blowhard Track to an obvious but unmarked track junction. Follow the track descending north. This drops steeply swinging ENE to the next forks downriver. At the river (ankle deep in normal flows) head 50m or so downriver and find marker tape on the northern bank.
A rougher track climbs ENE up the spur leading to pt1046. This is steep, marked with marker tape only and traverses loose rock-scree under the forest canopy. The track emerges into a scrubby clearing at around the 900m contour and ends. Follow the spur up through the clearing, and through another tongue of beech to a 2nd more open clearing beyond. Follow the eastern / south-eastern bushedge up to where it swings north, and cut through 20m or so of bush to intersect the obvious, marked Bob;s Camp Track.
Note: Described in the reverse direction to your journey
A good cut track runs most of the way between the Pinchgut Track and Bob's Camp Track, with just the northern end uncut/unmarked.
Turn off the Bob's Camp Track at the southern edge of the clearing south of pt1046 (visible 20m west of the track through trees). Follow the bushedge SW and then south - use a bearing of 190 degrees if you have a compass. The clearing ends - continue south (190 degrees) on a vague spur through beech forest to a second, scrubbier clearing. Follow the now-obvious spur south through this clearing to the southern bushedge, where marker tape marks the start of the track.
A well marked, rough track drops steeply SSW into the Garry in beech forest with loose rock-scree underfoot, swinging WSW to the forks with the creek draining pt1046. The only viable camping spots are 30m above the creek on the north side - a small terrace - the creek bed is steep-sided and narrow.
At the Garry, head 50m or so upriver and find marker tape on the southern bank. A steep but obvious track climbs WSW, swinging south to trig A9UM. The track is very steep and loose gravel at first, becoming merely steep later - and is marked with a mixture of old permolat and new marker tape.
