Police callouts in Halls Creek have halved since alcohol restrictions were introduced two years ago and drink driving charges are three times lower, according to a new Drug and Alcohol Office report.
The report, to be released in Broome today, details the benefits from the ban on takeaway sales of mid and full-strength alcohol.
Liquor Licensing director Barry Sargeant introduced the ban in May, 2009, after Aboriginal elders lobbied politicians over alcohol-related violence.
Assaults have decreased by more than half and there has been a 70 per cent reduction in presentations to the sobering-up centre.
Alcohol-related presentations to the Halls Creek Hospital emergency department have fallen by more than a third and a marked drop in sexually transmitted infections has also been reported.
Mental Health Minister Helen Morton yesterday announced five new drug and alcohol worker positions in Halls Creek to support the community into long-term change in the wake of the positive results.
She said the restrictions were "community led action at its best" and it was "hard to imagine how people would not be supportive" of them.
Robyn Long, who fought hard for the ban to remain in place after some business owners argued against it, said the report proved that reducing alcohol intake worked.
"(Halls Creek) has changed significantly," she said.
Ms Long said any loss of trade resulting from the ban needed to be weighed against saving children's lives.
"I would say that a child's life is a lot more significant than somebody's business going broke - if we can make a better future for our children, or our grandchildren in my case, then that's what we have to do," she said.
WA Police Commissioner Karl O'Callaghan said the results were "hardly surprising" and showed clear health benefits as well as a significant reduction in offending.
"It is self evident that where a community affected by widespread, generational alcohol abuse has a circuit breaker put in place, that the community will recover," he said.
"If we continue to be courageous enough to put community wellbeing ahead of business interests we will see remarkable progress."
