Nine months ahead of the long-awaited Coronial Inquest into the death of Tamworth teenager Mark Anthony Haines, New South Wales Police have announced a $1 Million reward for information relating to the death.

The $1 million reward for information pertaining to Mark Haines' death is an increase from the previous $500,000 and is due to NSW Police having received new evidence.

Today, Uncle Don Craigie, Greens MP & spokesperson for First Nations Justice Sue Higginson and Inspector Jason Darcy, presented outside of the Tamworth Police Station to announce the news.

The National Indigenous Times spoke with Greens MP Sue Higginson prior to the announcement.

"Today is really about Don and the Police standing together and saying 'this is it!' we now have a fresh Coronial Inquest which will be taking place in nine months and a new brief of evidence that has been handed to the coroner," Ms Higginson said.

"There has been some new work undertaken by detective and now there is an increase in the reward to a million dollars which is a very, very strong signal to everyone in the community far and wide that - if you know something, now is the time.

"We have as I say, new evidence and as Uncle Don has always maintained, the truth will come out because the truth always prevails. And so now it really is just a matter of time and that's why we are saying, it is nine months until the coronial.

"Any information that anyone has, no matter how small it is now is the time to come forward because it will help on this pathway to justice. There's a lot of pieces in the puzzle, we know that the police failed young Mark and has failed the families and the community through the investigation back in the eighties.

"When I say failed, there were many assumptions made, that were wrong, that were racist and that now, we saw the destruction of it, the loss of important evidence, but fortunately there was enough evidence that has survived and now there is new evidence and putting these all together we are now just asking for any further pieces, and this will all come round the table during the coronial in nine months time.

"At the end of the day, today is a significant milestone in the long windy rough road that Uncle Don and the family of Mark have been walking for thirty-five years. This is a very significant milestone and we are very encouraged by the actions of the New South Wales Police in taking this initiative and raising the reward."

The Haines family who have been campaigning for justice for their beloved teenager for thirty-five years, have always maintained that Mr Haines death was the result of foul play.

It was Saturday 16th January 1988, when the loveable teenager was found deceased on a railway track, outside of Tamworth under suspicious circumstances.

There were many flaws in previous investigations into the death, including a failure to take witness statements at the time and a failure to include vital evidence at trial.

Family and experts in the field have all agreed that the previous police investigation and Coronial Inquest were inadequate and that racism played a role.

At the time of Mr Haines death family members raised concerns and were told "You never know what a 17-year-old Aboriginal boy would do."

Gamilaroi Solicitor Karina Hawtrey from the National Justice Project had previously advised the National Indigenous Times that "A new investigation was opened around 6-8 years ago, and I understand that there has been police resourcing on it."

Greens MP Sue Higginson also praised the work of Investigative Journalist Allan Clarke.

"That incredible work really did uncover and piece together all of these components of vital evidence and by putting them all together, it really did provide us with a much clearer, more plausible reality and scenario about Mark coming into contact with foul play and now as soon as that really happened that pivoted all of the material in a particular direction which is what Uncle Don has been working towards for these thirty five years," she said.

"We are feeling that literally we are on the doorsteps of justice now."

Oxley Local Area Commander, Acting Superintendent Jeffrey Budd has said "We have received some useful information and support from members of the public on this investigation.

"Yet we believe there are still people who know exactly what happened to Mark but are either afraid, or unwilling, to share that information with police.

"If you have information that may help detectives with information surrounding the circumstances of Mark's death, please do the right thing and call Crime Stoppers on 1800 333 000," Acting Superintendent Budd said.
