Summary The IBA regularly supports the endangered Regent Honeyeater. It also supports small numbers of the near threatened Diamond Firetail, and the restricted-range Rockwarbler at the far north-west of its range.

Site description This IBA consists of land around Goulburn River National Park, north of Wollemi National Park, inland from Newcastle. The IBA includes Goulburn River National Park, Munghorn Gap Nature Reserve and private land west to Gulgong and Mudgee, being defined by a number of woodland remnants used by Regent Honeyeaters around Mudgee, Buckeroo, Home Rule, Meroo, Ulan, Wollar, Windemere Dam and Murrumbo. The Goulburn River NP extends along 80km of the Goulburn River. The average daily temperature varies from 15-30 Celsius in summer to 2-13 Celsius in winter and the average annual rainfall is 620 mm.
