The Opposition’s latest health pledge, costing $107.8m in additional funding, would see 278 paramedics and 72 ambulance officers join the SA Ambulance Service over the next four years.

Labor says the “unprecedented’ investment will allow the creation of eight 16-person emergency crews in metropolitan Adelaide and 17 across regional South Australia, including in “priority locations” such as Mount Barker, Victor Harbor, Goolwa and the Limestone Coast.

Over the weekend, Labor also promised to build a new $120m central SAAS headquarters in Adelaide which would include a new emergency operations centre, ambulance station and state health control centre.

The Opposition has now racked up close to $1b in health spending promises, following pledges last week to recruit 300 more nurses, 100 more doctors and build 300 more hospital beds across the state.

Labor said the latest investment was based on “feedback from frontline paramedics on the specific areas of greatest need”.

Opposition leader Peter Malinauskas, who last week tempered expectations that his party would be able to end ramping once and for all, said the state “need(s) to look after our emergency responders who do some of the most difficult and challenging work in caring for our community”.

“Labor will invest in this vitally important service for South Australians, boosting numbers of paramedics and ambulance officers and providing new infrastructure – and ultimately providing a better service for our community,” he said in a statement.
