The Leycester Creek, a perennial stream of the Richmond River catchment, is located in Northern Rivers region in the state of New South Wales, Australia.
Leycester Creek rises below Lofts Pinnacle on the southern extremity of Tweed Range about east by north of Green Pigeon Mountain, in remote country, north northwest of Nimbin. The river flows generally south and then east, joined by three tributaries including Back Creek, before reaching its confluence with the Wilsons River at the town of Lismore. The river descends over its course.[1]
