Machinery Creek

verified ACA 3B Moderate flood risk Cethana, TAS

Six-rappel descent through old mining country near Cethana, run on community-maintained anchors. The fallback when bigger Cradle canyons are blown out.

Open access, no commercial gatekeeping unlike Dove. The mining heritage is part of the character (rusted iron in the creek, concrete culvert exit) and the very minor metal pollution is documented but not a swimming hazard. Anchors maintained by Cradle Mountain Canyons even though it is not commercially run.

Logistics

Manager	Tasmania Parks and Wildlife Service (mixed tenure); anchors maintained by Cradle Mountain Canyons
Permit	No permit required. Park behind the Round Hill Cafe near the intersection of Cethana Road and Staverton Road, Cethana.
Distance	0.7 mi
Elevation	~250 ft loss
Time	3 to 5 hr
Technical	Six rappels, longest about 92 ft, through a series of chutes and pools. Optional 4.5 km shuttle for the exit. Final exit is either a slope climb or walking out through a concrete culvert. Old mine workings in the canyon, hence the name; expect sharp rusted machinery and very minor heavy-metal pollution. Native grade v3a2 II; ropewiki publishes ACA 3B II.
Season	Dec to Mar. Best done when other Cradle area canyons are too high; this drains a smaller catchment and runs cleaner at moderate flow.
Flood risk	Moderate. Smaller catchment than the Dove drainage but still alpine; check gauges before committing.
Vehicle access	Passenger sedan to the Round Hill Cafe car park. Optional shuttle covers the 4.5 km exit.
Crowd	Light. Open to independent parties unlike Dove Canyon, but not heavily trafficked.
Coordinates	-41.4772, 146.1499
