Respected health policy analyst Martyn Goddard has ‘rubbished’ Labor’s promise to build a new hospital at New Town for $160 million.

Mr Goddard has told the ABC Labor’s plan is ‘fanciful’.

Mr Goddard says it massively ‘underestimates the building cost’.

Labor’s thought bubble hospital plan is in tatters less than 24 hours after it was launched.

Labor has also been caught out underestimating the real cost of running such a facility.

Labor says it would be $20 million a year, but an initial analysis of the project puts the cost at more than $60 million a year.

Ms White has acknowledged staff to run the new hospital would take years to train and would have to be spread across existing facilities.

The proposal would gut the Royal Hobart Hospital and lead to longer wait times for elective surgery.

Ms White is now making things up as she goes along.

She didn’t even mention health in her campaign launch, and only started pulling together the New Town thought bubble last Friday.

The private company that owns the land and the hospital plans didn’t even know about Labor’s proposal until it was publicly announced.

It’s not a plan, it's a desperate last ditch uncosted unplanned thought bubble.
