On Saturday, it was announced property developers Traders in Purple were considering establishing a PTSD treatment centre at the former Australian Maritime College site at Beauty Point, which it owns.

A specialist centre could help address the shortfall between veterans needing treatment and available beds - but if it was in Launceston its placement between the Hobart and the North-West would make it relatively accessible for patients statewide, Ms Lambie said.

"Some of these people [Vietnam veterans] are now taking nearly three months to get them into a psychiatric unit," she said. "If they can't get them in [a psychiatric unit], they're putting them in the public health system. It's an absolute mess."

She said generalist psychologists were being discouraged from taking on veterans by the bureaucracy involved, as well as a pay disparity.

"I can tell you now, there's probably two psychologists that I know of around the state in the last 12 months who have closed their books to veterans because they just cannot take any more on," she said.

"It's the paperwork that they have to do with Department of Veterans' Affairs and the reports they have to write. And also there's a deficiency in how much they're paid [compared to psychologists for serving members of the defence force]."

The federal government has announced it will put $30 million into funding six Veterans' Wellbeing Centres: in Darwin, Townsville, Perth, Adelaide, Wodonga and Nowra.

Federal funding for a similar facility in Northern Tasmania was not off the table, Minister for Veterans' Affairs Darren Chester said.

"I am aware there is interest in establishing a similar Veterans' Wellbeing Centre in Tasmania and I have received representation from Tasmanian MPs, Bridget Archer and Gavin Pearce," he said. "As a veteran, Gavin knows the benefits these centres will bring and has provided suggestions for consideration."

"The government is committed to putting veterans and their families first and any further wellbeing centres will be considered as part of the budget process and will be designed in consultation with the ex-service community."
