Justin Elkington said Elk's Fishing and Hunting in Albury had seen a "massive" sales increase.

"It's everything - ammunition, firearms, fishing equipment," he said.

"A soon as Morrison had his address on Sunday night, people thought they needed to come in on Monday and get items as businesses might shut.

"I wouldn't say it was panic buying - I'd say people are getting the items to use over the next few months."

There has been panic buying of guns and ammunition in the USA with concerns it will impact local supply.

"I wouldn't say people are scared or protecting their homes, they just want to be organised," Mr Elkington said.

"If it does come to it, the resources are there to use.

"There are deer out there.

"If you've got a hunting licence, why not take meat and use it?

"People may need the meat to live off for a while and they want to have the equipment ready to go."

He said the business would continue to operate until told to stop.

A Blueys Hunting and Fishing employee said "people are doing a lot of buying at the moment".

"There will be more people with more time on their hands," he said.

Authorities stress there will be no food supply issues.

Compleat Angler Lavington owner Russell Mason said hunters and fishermen didn't have to rely on others for food. Bait sales have increased at the business.

"A lot of people like to source their own food through, more people will be doing that in earnest in the next few weeks."
