The party's health spokesman Jeremy Hanson says the nurse-led centre has not relieved pressure on the hospital's emergency department and has made the ED's problems worse.

He told Radio 2CC this morning that the walk-in centre was not working and that he would "probably" would scrap it if he became health minister after October's poll.

"Quite clearly the walk-in centre isn't working," Mr Hanson told breakfast host Mark Parton.

"It's quite evident that the walk-in centre located at the Canberra Hospital hasn't worked."

"So you would scrap it?" Mr Parton asked.

"I think we probably would Mark, because when you look at the evidence, and even Katy Gallagher is stepping away from the fact that it's going to be located at the Canberra Hospital,

"I think it's quite evident that it's made the situation there worse."

Chief Minister Katy Gallagher said yesterday that 32,924 people attended the walk-in centre between its opening in May 2010 and the end of May 2012. and that the service was an option for minor illness and injuries other than the emergency department or a GP.

"The nurse walk-in centre is popular with the community," Ms Gallagher said.

"I'm proud of how successful it has been and how many Canberrans have been able to use it," the Chief Minister said.

After coming under fire from a talkback caller this morning for a lack of policy direction, Mr Hanson said the Liberals' would be "negligent" to release policies before the budget was passed, a process set down for next month's sittings of the Legislative Assembly.

"We're in a position where the budget has not been passed, where the government has put us in a position where we're $320 million in deficit next year and I think it's prudent for us to wait until that issue is resolved, until we've got a budget passed until we go out with any substantive policies," Mr Hanson said.

"It would just be negligent, I think, when you've got information coming forward about things like the walk-in centres, for us to be pre-emptive about our policy announcements."
