The man, aged in his mid-thirties, was aboard a fishing boat in the Gilbert River, over 100 kilometres north of Normanton.
He was suffering from a suspected cardiac condition.
RACQ LifeFlight Rescue conducted a brief search along the river to locate the vessel, before landing nearby on the river bank.
The patient was brought ashore in a tinnie to be assessed by the Queensland Ambulance Service (QAS) Flight Paramedic.
RACQ LifeFlight Rescue airlifted the man to Mount Isa Hospital for further treatment.
Due to the extreme remoteness of the location, a helicopter extraction was the only means of rescue available.
The round-trip mission involved almost six hours of flying for the RACQ LifeFlight Rescue crew.
2018 was a record year for LifeFlight for lifesaving missions with its aeromedical crews, community helicopters and Air Ambulance jets performing a record 5,724 missions throughout Queensland and around the world.
