Dingo pack leader killed after mauling jogger on Australian island

A jogger was attacked and injured by a pack of dingoes on Fraser Island in Australia.
The attacked jogger, Sarah Peet, was flown to a mainland hospital in stable condition.
Wildlife authorities killed the lead dingo of the pack after the attack.
Dingoes on the island have become more aggressive due to being fed by tourists.
Authorities warn against jogging outside fenced areas due to the risk of dingoes chasing and attacking.
