Rae Harvey found herself trapped on a wooden jetty where her remote property meets the Clyde River as a firestorm terrorised communities on the NSW Mid South Coast on New Year's Day.

Rae Harvey was forced to leave her kangaroos behind as a firestorm hit She thought she was going to die before being rescued by her neighbour

She thought she was going to die before being rescued by her neighbour Medical supplies for the kangaroos arrived at the sanctuary yesterday

The animal lover was forced to retreat to the water's edge at Runnyford, near Batemans Bay, when flames engulfed her neighbour's home and blocked the only road to safety.

"Boom, it was on and we had nothing, we had to flee. It just came roaring, it went through my neighbour's place, and then he raced up here and said, 'It's already gone through my place … you have to go!'"

Leaving her beloved kangaroo sanctuary to burn, the former manager of rock band the Living End feared for her life as she stared into the orange glow on the river.

"I didn't think we were going to be saved — I thought we were going to burn alive."

"As we were leaving the property, the area we were sheltering in was on fire," she said.

Her neighbour, a volunteer firefighter, rescued her in a boat.

Ms Harvey left the music world to pursue her passion for rehabilitating injured wildlife through her charity Wild2Free.

She said she was more concerned about the kangaroos she was forced to leave behind than her destroyed home.

"I thought they're all going to be dead. There was so much smoke and fire and I didn't think they were going to be alive," she said.

Of the more than 100 marsupials she used to look after, only 22 are left — most of which are suffering from dehydration and critical burns.

"We cannot treat our animals because we cannot get the medications that we need to sedate them," she said.

"We need access to medical teams that we cannot get without prescriptions, and in a fire zone that's not available and the animals are going to die."

With power cut to vets and animal hospitals, Ms Harvey is calling for the Government to include injured wildlife in a national emergency response plan.

Some medical supplies donated from Adelaide found their way to the sanctuary yesterday.

Solicitor and volunteer Matthew Barlow picked them up from Sydney Airport yesterday morning and drove the 350 kilometres down south after responding to calls for help on the Wild2Free Facebook page.

"I picked up the burn creams, bandages and other supplies from Sydney Airport at 5:30am and drove them down to Runnyford," he said.

"I just hope this will help — but we need much more to save these poor animals."

A GoFundMe page has already raised more than $97,000 to help Ms Harvey rebuild the sanctuary.
