Protesters will gather at an immigration detention centre in Pinkenba to show solidarity with 35 detained refugees.
The 35 detained refugees were brought to Australia for medical treatment, after being detained on Nauru and Papua New Guinea for up to 6 years.
"They should have been processed under Australian law and given permanent protection in Australia," said organisers Refugee Action Collective Queensland.
The protest at Brisbane Transit Accomodation Centre will begin at 11am, Saturday, 1 May.
