A community rally calling for the reopening of the inquest into the death of Aboriginal teenager Thomas 'TJ' Hickey will be held at Walgett in northern New South Wales today.

Today would have been the 19th birthday of the teenager, who died in Redfern last year.

Two busloads of people from Sydney have travelled to Walgett to take part in the rally and about 100 people have been gathering at the Hickey family home.

Rumours that TJ Hickey was being chased by police when he lost control of his bike and became impaled on a fence sparked a nine-hour riot in Redfern.

A coronial inquiry cleared police of chasing the teenager.

But the Hickey family and their supporters will today march down the main street of Walgett to call for the inquest to be reopened.

Ray Jackson from the Indigenous Social Justice Association says there is evidence to show the teenager was being chased by police.

"We know that there is evidence out there that has not yet been presented to the coroner," he said.

"We have witnesses who have not been called, we most certainly want Michael Hollingsworth, the police office exempted from giving evidence, to give evidence."
