It came as Queensland's chief health officer Dr Jeannette Young said they must "hold firm" on the border shutdown but she could not guarantee it would reopen in September.
The Premier also stuck to her guns on when the Queensland border would open, with Dr Young backing up Ms Palasczcuk's plan to aim for September while continuing to review the situation.
"I, of course, completely agree with the Premier that September is a far more realistic one so if the tourist industry wants a realistic scenario then they should be preparing for September", Dr Young said.
"Queensland is an internationally renowned tourism destination which people travel from all over the world to experience for themselves, so the first stage is a flawless opportunity for us all to rediscover our state and fall in love with it all over again", she said.
Queensland borders may stay shut beyond September if COVID-19 cases around the country can't be brought under control.
"The State Government's roadmap told Queenslanders that interstate borders will open in July and that's what should happen".
"'I will always put Queenslanders first, that's my job", she said.
"At this stage, we're not sure whether that is a persistent case, or whether she's acquired it here", she said.
Intrastate travel is likely to be allowed from July if the Queensland curve remains flat.
"We really want to rescue something out of the winter season", he said.

Ms Jones said social media campaigns throughout the pandemic had ensured that Queensland remained top-of-mind for prospective tourists in NSW and Victoria who were planning holidays while in self-isolation.
"Having said that, I can't even commit that September will be possible, it depends what happens between now and then and it depends on every single Queenslander because you have followed the most onerous restrictions possible, you have done such a fantastic job and that's what's got us to where we are". It has been heartbreaking to make tough but unavoidable decisions - like the decision to close our borders and place hard restrictions on the industry - knowing that they would hurt while at the same time understanding they were critical to save lives.
More funding announcements are to come, with parliament resuming on Wednesday.
"It docked in the Sydney Harbour and from the Ruby Princess came the devastating price being paid by our state and by our nation and it is not for the NSW Premier to start criticising our Premier of our state for securing Queensland".
Trade Minister Simon Birmingham has urged states and territories to reopen borders for domestic travel in an effort to get the economy moving again. That would equal one month of zero cases.
Ms Palaszczuk said Australia's two biggest states needed to get their COVID-19 community transmission under control before visitors would be welcome in Queensland. I did a bit of research.
She said NSW was emerging from COVID isolation themselves.
"There is no advice in New South Wales to travel domestically to any other state", she said.
"We've got to protect Queenslanders, their health is my number one priority".
She said the advice at the moment was for workers to work at home into the future if they could, and that was to avoid a second wave.
