Koalas have a long history of occupancy across the Sydney Basin with local koala populations persisting in lands managed for environmental protection as well as in rural and heavily urbanised areas. This broad region supports several recently identified Areas of Regional Koala Significance (ARKS), namely;

• Campbelltown LGA/Wingecarribee LGA/Goulburn LGA
• Goodman Ford/Wiarborough
• Goulburn LGA/Shoalhaven LGA west
• Hawkesbury LGA
• Hunter region North
• Hunter region south/Sydney region north/Central Coast region
• Putty/Megalong

With new evidence of koalas colonies being found throughout the Sydney Basin bioregion continuously. 

Despite their enduring presence across the Sydney Basin, koala numbers have reduced dramatically over the preceding 20 years, resulting in the species being up-listed from Vulnerable to Endangered status in NSW, Qld and the ACT under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and Endangered under the Biodiversity Conservation Act 2016 (NSW) (BC Act).
