Despite two trials and a coroners' inquest, no one has been convicted of the crimes.
Families and supporters from across the country marched for justice at New South Wales Parliament House today as the Greens Party pushed for bi-partisan support for the inquiry.
The murders of two 16-year-olds, Clinton Speedy-Duroux and Colleen Craig-Walker, and four-year-old Evelyn Greenup in Bowraville 23 years ago still remain unresolved.
The trauma associated with this unfinished journey was voiced by the younger generations today on behalf of the Bowraville families.
"Twenty-two years ago I was only six years old, I can still remember sitting at my grandmother's house and listening to all my families sitting around crying and watching the news," Clinton Speedy-Duroux's cousin, Jasmine Speedy told NITV News.
"They'd found the body of Clint in shrub land, Clint was only 16 years old and he was murdered. This impacted my family in ways you couldn't imagine."
The New South Wales Government has been accused of being aloof in its response to the families' call for justice.
"What gives the Attorney General the right to tell us to walk away, to give up and get grief counselling? Who is he to tell us he is not going to support us, but most of all, what gives someone the right to murder three kids and get away with it?" says Clinton Speedy-Duroux’s nephew, Elijah Duroux.
"I'm hoping that Greg Smith as the Attorney-General will come out and give us what we've been asking for, and that is to [take to] trial the whole three cases as one, to allow the strike force investigation of the past 18 years and all the evidence that's been collated to be presented and to be heard in court as the new evidence, and as soon as we have that, we'll have our day in court, that's all we want." says Clinton Speedy-Duroux’s aunty, Ronella Jerome.
In the meantime, the New South Wales Greens hope a parliamentary inquiry will allow the families to tell their stories.
"No parliamentary inquiry can be a second murder investigation, it's not what parliamentary inquiries do," says NSW Greens MP David Shoebridge.
"We don't have a police force or investigators, but we are your democratically elected representatives, your representatives from everywhere, and we owe you a collective obligation to hear your evidence, to hear your stories."
Debate on the motion will take place in parliament next week.
