A girl has suffered a "significant leg injury" in a shark attack at a popular tourist spot in Australia, paramedics say.
A child has been bitten by a shark in Queensland's Whitsundays region, in the second attack in just 24 hours.
Doctor John Hadok, an off-duty emergency department doctor from Mackay Base Hospital, was able to attend the woman when she was pulled from the water, bleeding heavily from a wound on her leg.
The helicopter was due to arrive at Mackay Base Hospital by 8pm last night.
"From what I'd heard on the radio, I had no idea it was a shark attack", he said.
A RACQ CQ Rescue spokeswoman confirmed their chopper had been involved in a winch operation off a vessel at Sawmill Bay at Whitsunday Island, not Lindeman as was initially reported.
Queensland Ambulance Service Mackay operations manager Tracey Eastwick said the girl had been in a critical condition.
The RACQ CQ Rescue helicopter had been in the vicinity of the incident, tasked to a beacon search in Proserpine, when the four-man crew received the call, arriving on scene in 15 minutes.
Dr Hadok said his main role in the rescue mission was to assist with moving Mrs Barwick from the yacht to an inflatable dingy so she could be winched into the helicopter.
The woman reached the hospital complaining of significant levels of pain.
Last February, a Cairns father-of-two nearly died after he was mauled by a shark while spearfishing off Hinchinbrook Island.
"We landed on the beach of Whitsunday Island and the Whitsunday water police picked up our doctor and our paramedic, took them out to the vessel where she was and they got her into the boat and brought her back to the shore", she said.
Parts of the Great Barrier Reef are protected by shark drumlines, but a year ago a group of Sydney greenies started legal action to remove shark controls from the area.
"It is important to be aware that sharks inhabit the Queensland coastline, as well as estuaries, rivers, creeks, canals and streams - both saltwater and freshwater", the statement continued.
However, in other areas of north Queensland the shark control program targets Tiger and Bull sharks.
The Queensland government will set three drum lines in the Cid Harbour area tomorrow, in a bid to prevent any further attacks.
The girl was airlifted to hospital after being bitten on the leg while swimming in the Whitsundays in northeastern Australia, first responders said. Local authorities have reportedly warned holidaymakers and locals not to swim in the area.
