Police are working to quell racial tensions after a series of violent clashes in a multicultural community south of Brisbane.

Eleven indigenous people say they were forced to cower in the back room of their Logan home on Saturday night after Pacific Islanders, wielding machetes, metal poles, bats and bricks, attacked the home and threatened to burn it down.

The clash sparked another disturbance on Sunday night, resulting in two arrests.

Superintendent Noel Powers says police will patrol the street and meet with elders from both communities to stop the violence escalating.

While he insists the recent stoushes are an isolated dispute between two groups, he admits "rumours and innuendo" stemming from the incidents could further fuel existing racial tensions.

"I'd be a fool to say there isn't some tension between races in the Logan community," he told reporters on Monday.

"The Logan district is the most multicultural community in Australia.

"Where it escalates to and what the end results are I can't speculate on."

Indigenous man Greg Barlow, who was in the house during the first attack, said he feared the worst.

"What was going through our heads is we thought we would die because they threatened to burn the house down," Mr Barlow told AAP.

More than 30 people had banded together at the house on Monday, fearing it would be targeted again.

"They'll attack at night and they're going to be back, but we'll be here waiting for them for as long as it takes," friend Paul Butterworth said.

Mr Barlow said the attack was just the latest episode between Logan's indigenous and Pacific Island communities.

"We know it isn't going to stop and we can have all the meetings in the world with the police, but they just need to do their job," he said.

He said police had taken more than two hours to respond to calls for help on Saturday night.

Supt Powers rejected this claim, saying police were on the scene within half an hour and were delayed by having to respond to several jobs at once during a shift change.

Logan Pacific Islander elder Ofa Fukofuka denied there was problem between the two communities and maintained the city's youths were the real issue.

He told AAP because Logan was so multicultural, people tended to be identified by their ethnic groups.

"If there was real racial tension, these people wouldn't be able to live side by side like they do," he said.

"Everyone just needs to cool down and realise just because there is a disagreement between two youths from different groups, it doesn't mean there is tension between those groups."

Premier Campbell Newman has joined appeals for both communities to calm down.
