The Ambulance Employees Australia, Victoria Branch, report showed the survival rate of cardiac arrests in the shire was 35 per cent below that of Melbourne.

The report, presented to the Hepburn Shire Council, said there was usually one paramedic on duty in the shire, compared to up to six in Melbourne.

The report said "the population has increased significantly" yet the Daylesford Ambulance Station had the same capacity as when it opened in 1969.

Creswick, Clunes and Trentham residents often wait 20 minutes or more for an ambulance, the report said.

Rural Ambulance Victoria spokeswoman Jessica Smith said RAV worked to ensure "high-quality ambulance services".

She said RAV figures showed there had been no significant increase in caseload since 1999.

Ambulance Employees Association Victorian deputy president Steve McGhie said the union was concerned services did not match the shire's growing population.

"We have had no formal response but the government are aware of the issues," he said.

"Council can only support the position."

Council's chief executive officer Victor Szwed said issues of health were vital for all Victorians.

He said the council would write to the State Government, relevant minister and local state MPs seeking action to improve ambulance service resources within the shire.

"Support from council is sought to lobby the State Government to improve ambulance services so that response times are reduced in Hepburn Shire, and two qualified paramedics are available to all cases to allow for appropriate medical assessment and

treatment in a timely manner," he said.

Ms Smith said RAV monitored its resources according to caseload and sought funding accordingly.

She said RAV's number one priority was to ensure the community received the highest level of pre-hospital care.

"This ensures that we deliver a high-quality ambulance service to Victorians in regional, rural and remote areas," she said.
