A nine-year-old boy and his mother have been airlifted to hospital after being attacked by a dingo on Fraser Island off south-east Queensland earlier on Thursday evening.

A Queensland Ambulance Service (QAS) spokesperson said paramedics were called to the scene at Eurong on the eastern side of Fraser Island about 5:45pm, to treat the boy and woman for injuries to their arms and legs.

QAS said the pair were believed to be French tourists and it is understood both were bitten by the same dingo.

Spokesman Michael Augustus said the pair had just gotten out of a vehicle when they came across the pack of dingoes.

"The couple both panicked and ran back towards the vehicle and it was at that time when the pack actually chased them and attacked," he said.

The boy suffered "serious lacerations to his legs" and bite marks and injuries to his face, while his mother had "deep injuries" to her arms and legs.

Both patients were in a stable condition and were taken to the Sunshine Coast University Hospital by rescue helicopter.

The Department of Environment and Science said parks and wildlife rangers are investigating the circumstances of the incident and would increase patrols on Fraser Island to search for the dingoes involved.

"Rangers will also increase patrols at campgrounds and other island arrival points to warn visitors of the dangers associated with dingoes," a spokesman said.

Brian Guthrie from LifeFlight Rescue said the attack was an unfortunate incident.

"We very much feel for the people who have been attacked and the only thing we could recommend is to just follow the directions and recommendations by park staff and the signs that are out there," he said.

In January, a six-year-old boy was bitten multiple times by a dingo at Eurong.

The boy was returning to his campsite from an afternoon swim with his family when he encountered a pack of four dingoes.

One of the animals attacked the boy, biting him on the leg.

In July 2017, a 25-year-old woman suffered minor injuries after being bitten on the arm by a dingo at Lake Mackenzie, near the centre of the island.
