The Sunshine Coast based LifeFlight aeromedical crew today located a vessel 32 kilometres off the coast.

It was one three missions for the Sunshine Coast rescue helicopter crew.

The crew was tasked at around 8.30am by Australian Maritime Safety Authority (AMSA), after it was alerted to an Emergency Position-Indicating Radio Beacon (EPIRB). 

It is believed the vessel had engine troubles with the two adult occupants setting off the EPIRB.

The crew were able to communicate the location of the vessel to QPS water police and the Coastguard, who towed the boat back to the Sunshine Coast.

The crew was later tasked to airlift two motocross riders in separate accidents.

The first was a teenage boy who broke his leg, after crashing his bike while riding in a forest in the Gympie region, at around 11am.

The second was a man, aged in his 20s, who crashed his bike at a motocross park in the Sunshine Coast region and suffered chest and head injuries.

Both were treated by the LifeFlight critical care doctor and Queensland Ambulance Service (QAS) paramedics, before being airlifted separately to Sunshine Coast University Hospital in a stable condition.
