A group of Nazi sympathisers has plastered almost two dozen racist posters across Monash University, falsely warning Chinese students they’ll be deported.

CCTV vision revealed several people in dark clothing entering the campus and putting up the posters at about 7.30am on Monday.

The self-described national socialist group the Antipodean Resistance is believed to be behind it.

Monash University Student Association President Matilda Grey says she contacted security and all posters have been removed.

Police are also investigating.
