The Health Minister admits there have been flaws of the Victorian's ambulance services and would need improvements once new paramedics arrive under the government's regional ambulance policy.

The comments from Health Minister Daniel Andrews comes after the latest case of ambulance delays in regional Victoria where it took 90 minutes for an ambulance to arrive and transport a Kyneton woman to a hospital in Perth.

Anna Gallon, 46, was suffering a suspected stroke, and the ambulance got lost twice on its way to the hospital. Graham Gourley, the husband, used his iPhone application to track the directions of the hospital.

“The real concern is this is one story that I'm totally aware of,'' he said. ''There may be other stories and who knows, there might have been people who didn't survive because of delays. It's a joke.''

Mr. Gourley later criticized the Ambulance Victoria for its incompetence.

Ms. Gallon was later diagnosed with a brain tumor.

Ambulance Victoria defended that its ambulance took less than 90 minutes to reach the area, however, the delay would be investigation.

Mr. Andrews said the regional ambulance services had 1000 paramedics, 500 more than when Labor came to government.

''But I don't for a moment say it is a perfect system. We can always improve and we are committed to do just that,'' he said.

The ambulance policy will mean that Victoria will receive hundreds of new paramedics regardless of who wins November's state election. The opposition last week announced it promised a $151 million fund for more than 300 extra ambulance officers.

Mr. Andrews declined to comment on Ms. Gallon's case.
