Goanna kills dog, injures man in north Qld

A man has been seriously injured and his pet dog has died after they were attacked by a goanna at a popular north Queensland holiday destination.

The 72-year-old man and his wife tried to rescue their pet dog which was being attacked by the goanna near their Flametree home in the Whitsunday region about 3.30pm on Thursday, RACQ CQ Rescue said in a statement.

"The reptile suddenly turned on them, latching onto the man's right arm and leg as well as biting the woman's leg," RACQ CQ Rescue said.

The man suffered a serious laceration and possible fracture on his right arm and was severely bleeding from his leg.

He was flown to Mackay Base Hospital to undergo surgery on Thursday night.

The dog died after being attacked, an RACQ CQ Rescue spokeswoman told AAP.
