Camper Trailers Albury Wodonga Sales and Hire was down 95 per cent year-to-date at the end of October.

Owner Scott Fraser said the border being shut hurt more than COVID-19.

"No one could come from anywhere near NSW," he said.

"You only go 20kms north of the bubble and you had a 50,000 population.

"We got good rent assistance, but we're sole traders, so there was little [in government funding].

"Then with Gladys Berejiklian's border closure, she says to the NSW side of the border, 'If you're more than 75 per cent down I'll give you 10 grand'.

"But we're down 95 per cent because of the border closure."

Mr Fraser, who with wife Linda opened their business on Queen Street in Wodonga in 2017, said servicing helped them through COVID-19 restrictions.

Mrs Fraser said Easter bookings from 2020 had been rolled over to next year and then the border shut.

"We lost all of that June, July camping from NSW," she said.

"They had booked, and could camp, but they couldn't come to us."

But customers have come back in droves.

"Christmas, New Years is booked out," Mr Fraser said.

"Two of the last three sales have been people from NSW.

"With the camping industry, the next 12 months for us might get us back to where we were.

"There could also be a glut of secondhand campers and vans."

NSW businesses did it tough too, with tourism accommodation bookings down between 90 to 100 per cent and entertainment and hospitality revenues falling up to 80 per cent, according to data analysed by Farrer MP Sussan Ley.

Mr Fraser said it was important to remember businesses would take a long time to recoup those losses.

"I think it took a little while for Albury people to realise how we suffered," he said.

"Most of the people that lived in Albury and worked in Wodonga, they suffered just as much. You wouldn't want to do it again."
