One recent victim of two break-ins is calling for tougher penalties But the Chief Minister says criminals already face significant consequences

"Very similar to this sort of thing," he said, explaining the types of knives he says were stolen from his Camping World business in the Darwin suburb of Berrimah overnight.

"These are not toys, these are hunting tools.

"So [I'm] very concerned that these are now out in the community."

All up, Mr Thomas estimates at least 40 knives, ranging from machetes to hunting blades, were taken in the raid.

It's the second time in a month Camping World has been broken into, despite Mr Thomas spending almost $25,000 on repairs and increased security measures following the last incident.

"I don't know what to do here now," the exasperated business owner said.

"I've got electric fences, I've got roller doors, I've got cameras, I've got alarms, I've got caretakers."

The latest incident is one of more than 2,600 commercial break-ins across the Northern Territory over the past year.

Police are urging anyone with information about the Camping World break-in to contact them.

"There is no indication that the knives have been stolen for violent purposes," Detective Senior Sergeant Rob Jordan said.

Mr Thomas is urging politicians to increase the penalties for people involved in crimes.

"There needs to be consensus up in Parliament House to make the legislation tougher to bring these kids to bear," he said.

"People in the Territory are sick of it.

"We are sick of it as homeowners, as car owners and business owners.

"We can't afford to keep outlaying $40,000 every month to repair the damage."

Chief Minister Michael Gunner said criminals already face significant consequences.

"If you do the wrong thing you will absolutely face a consequence," he said.

"We know that from our incarceration rates at [the] Don Dale [youth detention centre] and the Holtze adult correctional prison."

Mr Gunner also said businesses affected by break-ins were eligible to receive up to $20,000 in financial support through the Government's Biz Secure program.

"We are saying we are happy to help the business be more secure and safe," he said.
