Victorians are already plotting to circumvent Queensland's tough border laws by parking their caravans in New South Wales for two weeks before entering the state.
Caravanning Queensland general manager Michelle Weston said park owners have been inundated with calls wanting clarity on the border laws restricting the movements of Victorians.
Queensland will open its borders to every state and territory but Victoria on July 10.
Anyone arriving from Victoria, or who have been there in the 14 days prior to their arrival, will either be turned around at the border or forced to quarantine in a hotel for two weeks at their own cost.
Ms Weston said Queensland caravan parks have been busy taking bookings since the announcement but also fielding questions from Victorians trying to get around the border laws.
"I've spoken to several caravan parks today who say their phones have been running hot, particularly with Victorians trying to find out if they spend 14 days in New South Wales can they then come into Queensland," Ms Weston told AAP on Wednesday.
"There are a large number of Victorians who call Queensland home over winter so with the border restrictions that will mean a lot of those may not be able to come."
Even if Victorians are put off travelling, a 'grey' storm is expected to sweep across Queensland's outback to end a drought of a different kind.
Queensland Tourism Industry Council boss Daniel Gschwind says an army of grey nomads from other states will hopefully flood the outback - where businesses are struggling - with cash.
"I've had reports of caravan parks on the New South Wales border being chock-a-block with caravans and motorhomes wanting to cross the border," he said.
"We are very optimistic that they will break the tourism drought of the outback."
The border reopening has reignited the passion on Nomads of Australia's Facebook page, says group administrator Frances Bischof.
She says grey nomads are booking parks nearer the coastline in the southeast of the state as a contingency against a second wave of COVID-19.
"People are sticking along the coastline rather than going inland or off the grid because they feel safer being closer to main roads to get home in case there is a need for them to return home," she said.
Victorians trying to make New South Wales home for 14 days before entering Queensland may be problematic, with penalties imposed on Melbourne virus hot spot residents who seek to cross the border.
