Trish Goss has spoken before about her battle with Centrelink for a sickness benefit while she was away from her job as a nurse undergoing treatment.

But she said the state government's Patient Travel Assistance Scheme was another bugbear during her cancer fight.

The Patient Travel Assistance Scheme allows for one flight to and from Flinders Island for radiation therapy, and one home visit when the treatment goes for more than six weeks. But the radiation treatments only go from Monday to Friday, and Ms Goss said she should have been able to go home on weekends.

A return flight from Launceston to Flinders Island is about $400, which is less than a week's worth of petrol reimbursements for someone driving from, for example, St Helens to Launceston, which is reimbursed, Ms Goss said.

"I wrote to the Health Minister, and what I said to them was, it should be the same for all Tasmanians," she said.

"In saying that, you have to be really grateful - and I am really grateful - and I'm sure everyone else is too, for the patient travel assistance we do get," she said.

"But it shouldn't be so black and white. They should take into consideration, have you got children. Have you got any dependents. Maybe it would be easier if I didn't have to leave my children and my home for seven weeks. I think it's really unfair for Flinders Island."

Flinders Island mayor Annie Revie said she had heard of a similar situation, of a husband and wife separated for about seven weeks while he underwent radiation therapy alone in Launceston.

"My understanding of it is that they don't fly you out and fly you back [for weekends], and for somebody with cancer that can be a very big issue," she said.

Health Minister Sarah Courtney was contacted for comment.
