An Aussie man on holiday in Queenstown pooed in a suitcase and spread faeces around his room in a backpackers hostel, police said today.

Senior constable Chris Blackford, of Queenstown, said the 25-year-old man was arrested at 2.30am today and charged with wilful damage in his Shotover St accommodation.

Police say the man defecated in a suitcase and spread faeces on the carpet, bed and curtains, left a condom lying in another guest's room and smashed a laptop.

He is expected to appear in the Queenstown District Court on Monday.
