Queensland has offered to take 3,500 Syrian refugees, almost 30 per cent of Australia's commitment.

In September, former prime minister Tony Abbott confirmed Australia would accept an extra 12,000 refugees affected by the conflict in Iraq and Syria.

The 12,000 permanent resettlement places will almost double the refugee intake this year compared to last year, and the boost is expected to cost the federal budget $700 million over the next four years.

Queensland Premier Annastacia Palaszczuk said she informed Prime Minister Malcolm Turnbull that the state was willing and able to provide homes and support services.

She told Parliament the Syrian intake would be in addition to refugees from other countries.

"The Syrian crisis has reminded me of the generosity of Queenslanders, and I've been so proud of the warmth of the public's response," Ms Palaszczuk said.

"Together we stand ready to share the privilege we all have the luxury of taking for granted - the privilege of calling Queensland home."

Multicultural Affairs Minister Shannon Fentiman said the state's system to settle refugees stood at the ready and had the capacity to act quickly.

"Just as we have stepped up before in times of crisis, we will welcome refugees into our Queensland community," she said.

"I have been touched by the sheer number of offers of help we are seeing, but not surprised.

"Queenslanders are generous of spirit and our multicultural state is one of our greatest strengths."
