Terminally ill Queensland man Mark Keans will see his four children on September 19

Mark's dad, Port Macquarie's Bruce Langborne confirmed Queensland Health had given permission for the visit.

The family is still negotiating on a number of conditions for the visit, with the Queensland government maintaining a hard line on border control due to COVID-19 restrictions.

Mr Langborne said the visit would coincide with a window of treatment Mark is undertaking.

"Mark goes back on chemotherapy treatment on September 23," Mr Langborne said.

"That would mean that we can't see him on or after that date anyway.

"It appears likely that we will start travelling up there next Thursday or Friday.

"I think that's when the reality will start to hit home: when we get together as a family and start travelling."

Mr Langborne said Mark "had had enough on Friday" and was considering going fishing for the day.

"I don't even know if he would have put any bait on the line," he said. "I think he just wanted to get away."

Mr Langborne says he's been amazed at the support the family is receiving, including a gofundme page to help fund their trip which has topped $230,000.

"I cannot believe how it (the fundraising page) has gone," he said.

"Even Scott Morrison has donated to it.

"Those funds will be used to cover our expenses but we will also be able to allocate some funds for the kids and to help other families in the same predicament."

Jamie O'Brien is organising this fundraiser on behalf of Tamara Langborne, Mark's sister.

The total on Friday afternoon had topped $231,797

Mark, 39, is terminally ill after being diagnosed with small cell cancer. He is receiving chemotherapy at the Prince Charles Hospital.

The Queensland government has come under increasing fire after it was revealed the family had been stopped from entering the state to visit their son.

The Langbornes were attempting to bring Mr Keans four children to see him but were advised they would have to foot the bill of around $20,000 for two weeks' isolation, and other costs.

It is understood that Mr Keans' family has made numerous approaches to Queensland Health to allow the visit.

All these approaches are currently under assessment with a final decision resting with the chief health officer's team.

Currently, no approvals or rejections have been issued to the family, at this time.

There are instances where exemptions are provided for interstate residents to visit family at the end of their life.

Those arrangements include the family leaving hotel quarantine to attend the visit while wearing PPE.

A Queensland Health spokesperson said they appreciate this is "a very difficult time".

"We understand and sympathise that this is a very difficult time and there are challenges," the spokesperson said.

"We are in the midst of a global pandemic and we need to protect our communities, especially the most vulnerable members of the community.

"Queensland's current border restrictions are in place for one purpose - to save lives.

"We understand the health directions in place are strict, but they are designed to protect Queenslanders from COVID-19."

Mr Keans four children live in Sydney are Mr Langborne is desperately wanting to get them to see their father.

"We want that visit to be in a way that he can interact with them," Mr Langborne said.

"It frustrates me that we just can't go and see him.

"It is a pity that the government and the public servants just aren't listening," he said.

"I believe the (Queensland) state government should look at these matters on a case by case basis.

"This isn't like we want to visit someone that has the flu.

"We also understand that there would be other people in the same kind of situation as us."
