State and federal politicians have promised to find funding for the Peel Health Hub after the clinic sparked concerns last week, admitting its nine services were struggling with a "significant growth" in clients.
The Mandurah Mail spoke with Peel Youth Medical Service (PYMS) spokeswoman Eleanor Britton, who said the Australia-first clinic, which opened in November 2018, was a "victim of its own success".
Ms Britton said the number of appointments made at PYMS, which helped young people with complex problems including mental health, drug and alcohol issues, had doubled since it joined other health service organisations at the Peel Health Hub last year.
Ms Britton said the Peel Health Hub needed funding to employ care coordinators to assess walk-ins so every young person would receive help.
Mandurah MP David Templeman said he hoped a "cocktail of funding" could be provided from various sources.
"I will continue to liaise with the health minister (Roger Cook) regarding this need," he said.
"I understand the need for additional support, particularly to providers for enhanced coordination of those accessing services there.
"The Peel Health Hub is delivering outstanding services to our local community."
Canning MP Andrew Hastie said he would write to state and federal health ministers and ask for their support.
"The Mandurah community would clearly benefit from an expansion of the Health Hub's services," he said.
"I've been a proud supporter of the Peel Health Hub since my first days in politics.
"The Hub's unique model has proved very successful and is fulfilling an important need for the health of our community."
WA Shadow Health Minister and Dawesville MP Zak Kirkup said he would attempt to secure funding for the care coordination team by lobbying Health Minister Roger Cook.
"It is an essential element of ensuring that our young people get the best possible help that they deserve, and it should be beyond politics," he said.
"What is disturbing is the high number of presentations to the Hub, which has resulted in them already reaching full capacity.
"It is critical that they are able to continue with this proactive approach for all our vulnerable youth, which not only provides early intervention to avoid escalation, but also reduces the strain on Peel Health Campus, which we all know is stretched beyond capacity."
Health Minister Roger Cook said the state government had provided funding for mental health in the Peel region.
"The McGowan Government, through the Mental Health Commission, funds the Peel Community Child and Adolescent Mental Health Service," he said.
"Last financial year we spent $1.9 million on the service to provide vital mental health support to children and adolescents up to the age of 18 years.
"Funding for primary health which includes the Peel General Practice and headspace are the responsibility of the federal government.
"I would welcome additional funding from the Morrison government to ensure the services provided meet demand."
