Ambulances are being ramped on the fourth floor of a car park at Flinders Medical Centre, in Adelaide's south, in what has been described as a "desperate measure" at the hospital.
The South Australian Salaried Medical Officers Association's chief industrial officer Bernadette Mulholland said she became aware of the issue recently, but had been told by staff that level four had been used for ramped ambulances for the past six-to-12 months.
