Bathurst ARC Fencing has donated thousands of dollars' worth of supplies to Secret Creek Sanctuary, which suffered extensive damage to its dingo fence and other animal enclosures from the Gospers Mountain bushfire which tore through the Lithgow area on December 21.

"I'm big on looking after our own," ARC Fencing branch manager Rob Lowe said.

Secret Creek Sanctuary owner Trevor Evans said most of the property surrounding the sanctuary, which is just north of Lithgow, was burnt.

The sanctuary provides a feral-proof enclosure where endangered native species are protected from predators.

"We had a bit of damage and lost one dingo fence, but we didn't lose any animals," Mr Evans said.

He said the wildlife was removed from the sanctuary and transported to Featherdale Wildlife Park in Sydney's western suburbs before the fire hit.

He said a few cars and a container of tools were destroyed by flames, but he was thankful no-one was injured and no buildings were lost.

"We lost chainsaws and drills, so it's all things that we need to fix the place - replaceable things," he said.

Bathurst ARC Fencing came to the rescue on Tuesday with the delivery of $10,000 worth of fencing supplies to help with the repair and recovery process.

Branch manager Mr Lowe said the company was doing an internal drive and team members across Australia were donating funds.

"Donations are being made by staff members to a GoFundMe page we've set up and the organisation as a whole will match dollar-for-dollar," he said.

"We distribute funds to organisations that staff members decide on and in the process someone mentioned the sanctuary, so we contacted them to see what we could do and what they needed.

"It turned out they needed fencing."

Mr Lowe said ARC donated around 1000 metres of fence line and some supports and extra wire to help with some of the sanctuary's current fencing.

"We wanted to get the supplies out here as soon as we could to help with repairs," he said.

He said he was pleased to help a not-for-profit sanctuary.

"It's fantastic. We couldn't get on board quick enough," he said.

Mr Evans said the Secret Creek Sanctuary had been blessed by the donation from ARC Fencing Australia.

"It's all come together and it's fantastic, especially being a not-for-profit sanctuary," he said.

"We run on donations and interest in general public.

"We thank them for their support."
