The intersection is a shared responsibility, with the Adelaide Road owned by the state government and Welch Road (the ring road) owned by the City of Victor Harbor. Waterport Road is in joint ownership between Alexandrina Council and the City of Victor Harbor.

Only last Friday, the Victor Harbor council met with representatives from the Department of Transport, Energy and Infrastructure (DTEI) to discuss the possibility of a speed limit reduction.

The mayor, Mary-Lou Corcoran, said that although a recent safety audit of the intersection does not support the lowering of the speed limit, the council would continue to press the issue with the DTEI.

"As development of our community extends further along the Adelaide Road, the merits of a lower speed limit will become more evident," she said.

"A reduction in the speed limit seems inevitable and we are trying to lock in an early timeframe for this to occur."

The officer in charge of Victor Harbor Police, Senior Sergeant Adrian Burnett, also agreed the safety aspects of the notorious intersection must be addressed.

"The speed limit must be reduced all along that area," he said.

Local emergency services, meanwhile, are no strangers to the intersection, having responded to four emergency calls at the intersection in the past five weeks.

Mark Ewens, the station manager of the Victor Harbor MFS, said the intersection would continue to claim lives if action is not take urgently.

Both Mr Ewens and Bob Suba, the unit manager for SES South Coast, agreed that the speed limit must be reduced to 80km/hr and a roundabout constructed.

"Something has got to be done; it was the second fatal accident in 12 months and minor accidents happen all the time," Mr Suba said.

"In the end, we need a roundabout, but how many lives do we have to lose before that happens? We've lost too many already."

A spokesperson for the DTEI would not comment as the crash is the subject of a police investigation and that another safety audit will be conducted once the investigation is complete.
