One of the men involved in the so-called Palm Island Airfare Affair today demanded the Queensland police service bring an end to black injustice on the island.

Brad Foster, the chief executive officer of the Carpentaria Land Council, issued a statement yesterday demanding answers from Queensland Police Commissioner Bob Atkinson.

The Aboriginal activist, who visited Palm Island following riots which erupted after the death in police custody of 36-year-old Cameron Doomadgee, wrote to Mr Atkinson today with a list of questions.

Mr Foster said Aborigines were still being detained for lengthy periods and police were heavy handed in their treatment of the island's black residents.

"There is still a large contingent of police complete with riot gear present on Palm Island and it is a situation of confrontation, rather than reconciliation," Mr Foster wrote.

"Why are people being detained in custody for long periods of time without access to legal representation on the island?

"Is the Queensland Police Commissioner aware of accounts of police storming into people's homes with young children and babies present.

"On one occasion, a pregnant woman and grandparents were forced to lay face down on the ground. Can the Queensland police commissioner advise why other policing options have not been attempted?"

Mr Foster also wanted to know why counselling was not made available to members of the Doomadgee family and what processes police were following to ensure better relations with locals.

"The situation on Palm Island could be construed by any reasonable person as a tense and excessive response to the Aboriginal community's grief regarding the circumstances of the death of Cameron Doomadgee and I look forward to the Queensland Police Commissioner's response to these matters," he said.

A police media spokesman said Commissioner Atkinson would consider responding once he received the letter.

"He will read the letter and deal with it in the appropriate fashion," said the spokesman.

Last week, Mr Foster was embroiled in controversy when he claimed, with fellow activist Murrandoo Yanner, that he was offered a free airfare to Palm Island and was never asked to pay it back, as the government claimed.
