Late last night, an Australian Army MRH-90 helicopter impacted waters close to Hamilton Island.

A search and rescue commenced immediately.

Sadly, the four aircrew who were on board are yet to be found.

The families of the four aircrew have been notified of this incident.

Our first thoughts are with the loved ones of the missing.

All Australians hold them in our hearts and we hold onto hope as the search and rescue teams go about their work right now. We have the utmost confidence in their professionalism and skill.
