A veteran shark hunter is trying to offload a frozen, five-metre great white that he killed nearly 30 years ago for $30,000 on Gumtree.

Vic Hislop has dedicated most of his life to capturing and killing sharks, but is finally parting ways with a trophy catch - which he picked up off the coastline of Queensland's Hervey Bay in 1988.

For the past eight years the enormous apex predator has sat in a custom-built refrigerated trailer in his backyard, but the seasoned fisherman is hoping to find a new home for it.

'Now is your chance to own it and reap the rewards as a traveling display or use our imagination (sic) even pride and joy in your mancave,' the Gumtree ad read, according to Riptide Magazine.

Before the trailer, the shark spent over two decades entertaining the crowds at Mr Hislop's quirky 'Shark Show' in Airlie Beach - but once that shut down he had to transport it to his home.

'It has been in my backyard since the shark show closed down in Airlie,' Mr Hislop said.

'It is pretty hard to get rid of something like that. It has cost me thousands of dollars in electricity to keep.'

But selling a decaying frozen fish that has been a protected species for over 15 years on an online classifieds website hasn't come without its hitches.

The advertisement has since been taken down from Gumtree, after shark conservationist Madison Stewart brought it to the attention of the Department of Agriculture and Fisheries.

'I reported to fisheries and they got back to me today saying it Is ILLEGAL,' she shared to her 5,000 friends on Facebook.

But Mr Hislop believes he is well within his rights to sell the shark, which he caught long before great white's became a protected species in 1999 under Australian federal law.

A spokesman for the Department of Agriculture and Fisheries told Daily Mail Australia that it was investigating the matter.

'The Department are aware of this matter concerning the sale of a Great white shark and have been in touch with Mr Hislop. Great whites are protected under state and commonwealth legislation,' he said.

He says it has cost him thousands of dollars in electricity bills to keep the shark

According to Gumtree's policies on wildlife trade, selling great whites is not allowed.

'The trade of protected species (native or exotic), and the sale of products made from protected animals or plants, is not allowed on Gumtree,' the policy reads.

'Gumtree takes this matter very seriously and any ads reported to us for breaching these regulations will be removed from Gumtree.'

Mr Hislop still holds high hopes for selling the shark, but isn't willing to ship it internationally.

'A bloke rang me from China and wanted to know about it. But I don't think I will go through the trouble of trying to send it to China,' he told Riptide.
