A small but angry group of protesters have gathered outside the New South Wales Parliament as part of their campaign to re-open the inquest into the death of Thomas "TJ" Hickey.

The protesters called for Premier Bob Carr to meet them.

They claim that the Aboriginal teenager was being chased by police when he became impaled on a fence in the inner Sydney suburb of Redfern early last year.

However, a coronial inquest has cleared police of any wrongdoing.

TJ's mother Gail says despite Mr Carr's refusal to have the inquiry reopened, she will not give up.

"I'll be fighting until the day I die to get the inquest reopened," she said.

The group marched through the western NSW town of Walgett on Wednesday to the grave of TJ, who would have turned 19 that day.
