The Wollemi Creek, a partly perennial stream of the Hawkesbury-Nepean catchment, is located in the Central Tablelands and Blue Mountains regions of New South Wales, Australia.
The Wollemi Creek rises below Kekeelbon Mountains on the southern slopes of Mount Mounundilla, within the Wollemi Range, in remote country within the Wollemi National Park, north northwest of the locality of Putty. The river flows generally south southeast and south southwest, generally adjacent to the Putty Road, joined by seven minor tributaries before reaching its confluence with the Colo River in the upper reaches of the Colo Gorge, about south southeast of Glen Davis. The river descends over its 84km (52miles) course.[1]
The upper Wollemi Creek has two main sources, one originating at about altitude east of Mount Monundilla, and the other due south of that mountain. Both flow through rough deep gorges at about in permanent dry weather flows, and fast flowing flood, until their confluence at about, due west of Putty, from where the creek flows eventually into the Colo.
The primary inhabitants of the upper creek are yabbies, eels, and possums. Some ancient massive gums populate the lower gorges and very few signs of non - native infestations are apparent, one notable exception being mistletoe which infests the upper branches of the oldest trees.
