A decade after the death of Thomas "TJ" Hickey, passions remain strong in the Sydney suburb of Redfern.

The Hickey family and supporters will today mark the anniversary with a rally to demand an apology from the New South Wales Parliament over the 17-year-old's death.

They are also seeking permission to mount a controversial memorial plaque at the fence where the teenager was impaled in 2004.

TJ's death sparked a nine-hour riot in which Redfern railway station was set on fire and police were pelted with rocks, bricks and bottles, leaving more than 40 officers injured.

Following an inquest, a coroner found no evidence the teenager, who was riding his bicycle, was being pursued by police when he died, even though a police car had followed him down a pathway.

Coroner John Abernethy found the death was due to a "freak accident" and police were not responsible.

The Hickey family disagrees with the findings.

They maintain TJ was chased to his death by police and have spent years campaigning for a fresh inquest.

Ray Jackson from the Indigenous Social Justice Association, which is organising today's march, says he has written to two government ministers seeking action.

He says he has asked Police Minister Mike Gallacher to intervene in the long-running dispute over the wording of a memorial plaque.

Mr Jackson says the Hickey family has created a plaque stating TJ died as a result of a police pursuit, but Redfern police will not agree to it being placed at a memorial site.

"Why change history? Why change the facts of how her son died? TJ died as a result of a police pursuit. TJ's bike was rammed by a car driven by a Redfern police officer. She's not going to change that just to mollify the sensibilities of Redfern police," he said.

Mr Jackson says he has asked the Mr Gallacher and Attorney-General Greg Smith to greet the protestors when they arrive at Macquarie Street but expects his request to be ignored.

He insists that will not stop the campaign for justice to be served.

"If we don't get an apology, if we don't get permission to put the plaque up, if we don't get a new investigation and a new inquest, we will continue the struggle for 11 years, 12 years, 15, 20, 25, 30 years," he said.

"However long the Hickey family wishes to march, we will march with them."

Mr Jackson says he is seeking a parliamentary apology to the Hickey family, similar to the one given last year by the West Australian Parliament to the family of John Pat.

The teenager died in police custody at Roebourne in north-west WA in 1983.

Four police officers and a police aide were charged with the 16-year-old's manslaughter but were all acquitted at trial.

Mr Jackson says the Hickey family needs similar recognition that a wrong has been done and hopefully will not have to wait 30 years for it like the Pat family.

"If you read the apology from the Western Australian Government it does not admit to any blame on behalf of the police. What it says is we recognise your sorrow and we're sorry for it," Mr Jackson said.
