Supporters of the bilby are vowing to keep fighting in the wake of the deaths of scores of the threatened marsupials and serious charity funding woes.

Earlier this year a specially-built bilby fence in remote western Queensland was damaged by floods.

Frank Manthey, the co-founder of the Save the Bilby Fund, says feral cats breached the barrier and killed scores of bilbies.

"We weren't vigilant enough to pick it up quick enough, but the cats did," he told 7.30.

"When we discovered they were in there, it was too late.

"We estimated we could have had around 150 newborn bilbies inside that fence, and they've cleared the lot out."

Although the fence has been temporarily repaired, Mr Manthey explained to a recent Senate committee that the Queensland bilby population is under siege.

"We have shot 3,000 cats in something like 16 days just around where the bilbies are," he said.

More recently the Save the Bilby Fund was dealt a blow when Darrell Lea chocolates collapsed.

"We lost our major sponsor, Darrell Lea, sadly, and we were getting around $50,000 a year," Mr Manthey said.

Darrell Lea's sale of chocolate bilbies in the lead-up to Easter was the biggest single revenue raiser for the bilby fund.

Mr Manthey says he was so distraught that he toyed with the idea of seeking help from overseas.

"I was all lined up to go to China to see if I could get chocolate bilbies made in China," he said.

"How sad would that have been?"

But we will not be seeing Chinese bilbies this Easter.

The fund has now secured a new sponsorship with a Melbourne-based chocolate manufacturer.

Steve Curnow, the secretary of the Save the Bilby Fund, says Mr Manthey should take full credit.

"Frank did most of the work, he's a pretty passionate sort of guy," he said.

"Very persuasive, it's hard to argue with him."

The birth of triplet baby bilbies on the Gold Coast provides more positive news to supporters of the threatened species.

Mr Manthey says the bilbies are believed to be the first triplets born in captivity.

They were born at Dreamworld late last year as part of a captive breeding program, and made their first public appearance today.

Mr Manthey says the joeys' mother Jessica is named after solo sailor Jessica Watson.

"She's been a brilliant mum. And now that they are out of the pouch we can start feeding them softer foods," he said.

"Their battle is won, Jessica has won that in the pouch. I've seen one photo and they just look absolutely adorable."
