A photo of the incident, shared on their Facebook page, included a caption stating: "NSN would like to thank the student body and faculty for letting us promote National Socialism on campus without opposition.

Members of the NSN marched down Spring Street, displayed a banner, performed Nazi salutes on the stairs of Parliament House, and referred to transgender people as paedophiles.
