"What more do we need to do to get justice?"

A petition that accuses the legal system of failing to provide three New South Wales Aboriginal families with justice after 21 years was last month presented to the state government.

The document relates to the cases of two 16-year-olds and a four-year-old who were murdered over a six month period in 1990.

They are 16-year-olds Colleen Walker and Clinton Speedy and four-year-old Evelyn Greenup - all from Bowraville on the north coast of NSW.

A man was charged but not convicted for the crimes.

No-one has since been convicted despite several trials and a coroner's inquest.

The petition, presented by families of the victims, aims to continue the pursuit of justice for the town's Indigenous community.

Spokesperson for the families Leonie Duroux says the petition shows a loss of faith in the justice system, and argues not everything has been done to see justice prevail.

Leonie Duroux:

The petition's partly come out because of the time that it's taken and the frustration levels of the family. Quite often we've asked questions and we get the same answers back that are basically fob offs. So, I think after 21 years, the families deserve direct answers and proper answers. So, I hope that we'll get those answers.

The cousin of one of the victims, Melinda Hooper, says she is also frustrated with the lack of action on the cases.

Melinda Hooper:

I feel angry. I feel that, at this stage, 21 years on and we're still hitting our heads against a brick wall because we're not getting any closer to getting justice for what happened to the three Koori kids that went missing from the same community. We're trying to do the right thing by voicing our concerns with the right people - with law firms, with the Attorney-General's department, and even doing the petition and stuff. But it feels like, "what more do we need to do to get justice for these three kids?"

Voice ends.

A spokesperson for NSW Deputy-Premier Andrew Stoner says any resolution to the matter would be welcome.
