War medals were stolen from a home when it was robbed in Greystanes last week.
The medals are the property of an Australian soldier who had served in Afghanistan.
Holroyd police have published images of the stolen medals on its facebook page and are appealing to anyone with information to contact them.
One officer said stealing the medals was a cowardly act because they honoured an Australian who had served their country.
