A confronting short film that showcases the shocking alcohol and drug-fuelled violence experienced by WA's most vulnerable communities will be shown to Prime Minister Malcolm Turnbull in the hope of prompting an expansion of the cashless welfare card scheme.

The video was commissioned by outgoing Police Commissioner Karl O'Callaghan, community leaders and the Minderoo Foundation.

It uses CCTV and police footage from several WA towns to highlight what it calls "war zone" conditions experienced by children living in the regions.

One clip shows an adult male picking up a limp child by their hair and placing them in a shopping trolley.
