The boy bashed some of the reptiles to death with stones and threw other living animals over the wall into the crocodile’s enclosure.
The seven-year-old is reported to have killed a turtle, four Western blue-tongued lizards, two bearded dragons, two thorny devil lizards and the zoo's 20-year-old goanna lizard.
Apparently the boy managed to avoid security alarms when he broke into the centre and began his cruel rampage.
The zoo is considering suing the boy’s parents because under Australian law he is too young to be prosecuted.
