Two new critical incident helicopters that will conduct lifesaving aeromedical evacuations will be operational across Australia's Torres Strait within a matter of months.

The H145 will provide a critical uplift in capability for South Australia Police, giving officers on board the tools they need to fulfil their duties to maximum effect.

The renewed partnership, which first commenced in January 2016, will ensure AV continues to provide safe, timely and expert patient care during some of Victoria's most logistically complex emergencies.
