Paul is the first koala to receive treatment after being rescued from hectares of scorched habitat at Lake Innes and treated at Port Macquarie's Koala Hospital.

The loss of significant core koala habitat in the 2880 hectare fire has been described a national tragedy.

The Crestwood-Lake Innes fire, which started one week ago after a lightning strike is now under control. It is a miracle no homes or lives were lost but the impact of the blaze on this important wildlife corridor will not be known for weeks.

Paul's fur is singed and his feet and hands are burnt.

He is pictured here receiving some fluids from the Koala Hospital's dedicated volunteers.

"Our qualified search and rescue volunteer teams are working closely with Fire and Rescue, Rural Fire Service, Port Macquarie-Hastings Council and National Parks and Wildlife Service to collect burnt or injured koalas and other fauna for treatment and care," a spokesperson said.

Experts estimate between 200 and 350 koalas died when the fire ripped through crucial koala habitat.

Just over two-thirds of the fire ground footprint is prime koala habitat.

The koalas in that area are of national significance due to their genetic diversity.

The Lake Innes State Conservation Area and Lake Innes Nature Reserve hold the most important populations of koalas in NSW.

The destruction of habitat means koalas can't use the area for a long time.
