Queensland police have raided three properties after racist and neo-Nazi graffiti and banners were displayed in a southern Brisbane park.
The far-right symbols were put up in the Calamvale District park between 6pm on February 3 and 6am the following day.
Detectives launched three raids on Brisbane's south side and seized a number of items on Friday.
No one has been arrested or charged.
Police said they were continuing to investigate the racist and neo-Nazi symbols and appealed for any information.
"Everyone in Queensland has a right to feel safe, to not feel threatened or victimised and the Queensland Police Service remains committed to supporting people across our culturally diverse society," officers said in a statement on Monday.
"The Queensland Police Service urges anyone who feels threatened or fearful by the actions of others to contact police."
