Queensland boy airlifted after snake bite

A young boy has been airlifted to hospital after being bitten by a snake on Queensland's Darling Downs.

The boy told paramedics he opened a screen door and stepped on what he described as a brown snake north of Toowoomba on Monday morning.

An RACQ CareFlight Rescue crew transported the boy to the Toowoomba Base Hospital in a stable condition after he was treated at the scene.

It is the third snake bite incident involving the rescue chopper in just 10 days.

A 20-year-old Sydney woman was flown to hospital after being bitten on Fraser Island last Wednesday, while a 10-year-old boy was taken from the Warwick Hospital to Brisbane's Mater Children's Hospital after being bitten on October 10.

The incidents have prompted calls for people to be aware of first aid procedures for snake bites.

Patients should be immobilised after the bite, CareFlight chief medical officer Dr Allan MacKillop said.

"Wrap a crepe bandage right down the limb and immediately call triple zero," he said.

Dr MacKillop also discouraged patients from attempting to catch or kill the responsible snake.
