The patrols resolve public conflicts, stopping Aboriginal people from clashing with police and linking them with support services.
They take children who cannot go home to safe houses.
The Patrol’s two southeast bus patrols stretch from Burswood to Armadale, but focus mostly on Cannington and Gosnells.
It had received Federal funding since 2001 but its latest application for funding was unsuccesful.
State funding will not be assured until the State Budget is delivered on August 8.
Nyoongar Patrol chief executive Maria McAtackney said as things stood, two southeast patrols would become one and Fremantle and Midland would lose a day each.
She said the three full-time office staff would shrink to her full-time job and one part-timer, making service co-ordination harder.
Officers also patrol the northern corridor, City of Vincent and Northbridge.
‘The Government talks about ‘closing the gap,’ looking at education and employment to reduce disadvantage, then decides it’s not a priority to keep Aboriginal people from getting arrested,’ Ms McAtackney said.
An Attorney-General’s Department spokesman said the Patrol’s funding application was unsuccessful in a ‘highly competitive’ round that had 248 applications, more than double that of previous rounds.
He said services applying were assessed in terms of demand, their ability to deliver, connection with their community, Federal and State agency support and their ability to measure success, manage risk and use funding well.
He said organisations that had previously received funds were subject to extra reviews.
