Koalas have lost more than 5000 hectares of habitat in northern NSW since laws which protected native vegetation were axed, a report has found.
The report by wildlife conservation group WWF and the NSW Nature Conservation Council found since the repeal of the state's Native Vegetation Act in 2017, the rate of native bushland clearing in Moree and Collarenebri has nearly tripled.
The NSW government replaced the law with controversial land-cleared codes which allow property owners to clear sections of native bushland without prior environmental assessment.
The NCC and WWF compared satellite images of 22,173 sq km of land around Moree and Collarenebri for the report, which was released on Friday.
The extensive clearing of koala habitat is "detrimental" for the popular species which is listed as vulnerable to extinction, WWF-Australia conservationist Stuart Blanch said.
He warned that koalas faced extinction in NSW as early as 2050 with 5246 hectares of koala habitat around the two farming communities destroyed between mid-2017 and mid-2018.
"We have to stop this excessive tree-clearing if we want to keep koalas alive in the wild for future generations," Mr Blanch said in a statement on Friday.
NSW NCC chief executive Kate Smolski said the report was just the "tip of the iceberg" as it only looked at a fraction of the state.
