Senator Lidia Thorpe has backed calls by a WA community for early intervention and a holistic approach to guide children at risk away from the criminal justice system.

The Shire of Carnarvon, in Western Australia's Midwest, unanimously passed votes of no confidence in the WA and federal governments on Tuesday for "widespread failures" to address the causes of youth crime.

The ABC reports that the vote came shortly after the car of North West Central MLA, Merome Beard, was allegedly stolen by three boys on the outskirts of Carnarvon on Sunday night.

Ms Beard described the incident as confronting. WA Police have charged three boys aged 12, 15 and 16 over the alleged theft of the car, which was allegedly later used in a ram raid robbery of a bottle shop.

The Carnarvon council's motion also demanded immediate action for early intervention programs, restoration of key wrap-around services, and increases to funding for social housing, crisis accommodation and mental health services.

Senator Thorpe said it was "positive to see Carnarvon community, including local Liberals, defining 'action on youth crime' as more early intervention and wrap around programs".

"We need more communities demanding supports which work, not more of the failed punitive approaches," the Gunnai, Gunditjmara and Djab Wurrung senator said.

Ms Beard, a Liberal MP, said the alleged incident on Sunday had highlighted a need to take action addressing youth crime by increasing the level of wrap-around services in the region and across the state.

"The Department of Child Protection does a wonderful job but they're skinny on the ground," she said.

"They don't have resources, support, leadership and the senior management teams they need around them."

Shire President Eddie Smith told the ABC: "Carnarvon's not in a crisis but if we don't do something we … don't want to head in that direction."

Liquor Stores Association of WA chief executive Peter Peck told the ABC current laws and approaches to youth and alcohol-based crime came from a misconception.

"The problem is, if you look at the amount of coverage [services] we have in regional WA, it's actually gone down (since the Banned Drinker's Register was introduced)… If we take away alcohol, that's alright, but if we don't replace it with a therapeutic service, then we're never going to change anything," he said.

WA Police Minister Paul Papalia said crime in the town had decreased since the restrictions began.

"In the first 12 months the total number of offences in Carnarvon halved, including a 75 per cent decrease in family and domestic violence," he said.

A spokesperson for federal Attorney-General Mark Dreyfus told the ABC the Commonwealth had announced 27 justice reinvestment initiatives across Australia, including one in Carnarvon.
