Kangaroos have been on the attack, with tourists north of Sydney sustaining large, deep cuts to their back, face and torso.
A warning has been issued to tourists, urging them to avoid feeding the animals on the grounds of the Morisset Hospital due to the attacks.
Lake Macquarie MP Greg Piper has posted footage on his Facebook page showing tourists feeding the animals.
The video then cuts to images of the serious injuries these people have sustained.
The kangaroos can be seen lashing out with their hind legs and using their razor sharp claws to attack.
According to Mr Piper, one person has had to have 17 stitches on their face after being attacked.
