Asked why he shot a koala, stuffed it and hung it on a wall in his home, a Victorian man told investigators it was "something to do".
The Kilmore man found the koala on the side of a road at French Island and shot it with a .22 rifle, Seymour Magistrates Court was told on April 27, in a case recounted by Department of Environment, Land, Water and Planning on Monday.
The man took the dead animal home and stuffed it himself before mounting it on a wall.
Wildlife officers discovered the koala during a raid of the property in June the previous year.
When the man was interviewed and asked why he killed the koala, he said it was "something to do," department spokesman Greg Chant said.
"We take these matters very seriously and it's disturbing that somebody would kill a native animal in these circumstances," Mr Chant said in a statement on Monday.
The man denied charges in court but a magistrate found him guilty of illegally destroying and possessing wildlife, in a breach of the Wildlife Act.
He was placed on a good behaviour bond, with a condition that he make a $1000 contribution to a court charity fund.
