The timeline for the arrival of three new regional ambulance helicopter bases remains unclear as a public hearing reveals funds have not been allocated to run them.

Before the NSW election in March 2023, the government committed to $70 million to build the bases.

A NSW budget estimates hearing on 2 December heard that almost $64 million has been earmarked for construction, which is yet to begin.

Asked by Nationals Upper House Member Wes Fang when the first base will be up and running, NSW Ambulance Chief Executive Dr Dominic Morgan said it will depend on future funding for operations.

"Work has been done in identifying the locations that have been modelled. That now has to be considered by the Government. Part of operationalising those bases is to secure ongoing funding," Dr Morgan said.

He also said it usually takes two years from commitment to deliver a new helicopter, although there may be "other options" if the governments want them sooner. Dr Morgan did not specify those options.

Dr Morgan said NSW Ambulance has identified four priority locations, but did not reveal them due to 'Cabinet in confidence,' meaning information that is currently confidential within the government.

The government will consider an assessment for three of the four priority sites.

“We look forward to sharing more about the delivery of more ambulance helicopter bases in due course,” NSW Minister for Health Ryan Park said when approached by the Western Plains App.

Mr Fang said the government hadn't thought past "the bricks and mortar."

“In my experience as a former ChildFlight rescue helicopter pilot I know all too well that these bases can’t function without the adequate operational funding and staff."
