The men, aged between 18 and 32, were each charged with murder and will appear in court on Thursday.
Ten men have been charged over a stabbing attack in Brisbane's north earlier this week that left a 19-year-old man dead and 10 others injured.
The group of men, all aged between 18 and 32, allegedly confronted another group who had gathered in a Zillmere park around 5.30pm on 13 September.
Police executed several warrants across Ipswich and South Brisbane on Wednesday morning, taking the men into custody. Three vehicles have also been seized since Sunday.
The men were each charged with one count of murder, 12 counts each of acts intended to cause grievous bodily harm and one count each of affray and disobedience to lawful order, Queensland Police said in a statement on Wednesday night.
They will appear in the Brisbane Magistrates Court on Thursday.
Leaders across Brisbane's African communities have been assisting police with their inquiries.
Beny Aterdit Bol, president of the Queensland African Communities Council, earlier told SBS News the South Sudanese community was left distraught by the “unexpected, very tragic incident".
“The community is so shocked, it's very upset,” Mr Bol said.
“A young person lost his life, a young person who had a bright future.”
Detective Superintendent Tony Flemming told reporters earlier on Monday those involved in the incident appeared to be "outliers in the African community".
"The advice I have is that they are not supported generally by the African community," Mr Flemming said.
Mr Bol, who also works in Youth outreach, said Brisbane’s South Sudanese community is not unique in struggling to engage some of its young people.
“We have been aware that some young people are becoming disengaged. Those are young people from different backgrounds, not only African,” he said.
“We do not have a history of young people getting together and engaging in fighting of that nature.
“As a community, we need to understand the causes of this and work closely with families and community members to get to know what's going on.”
