A Launceston women's shelter had to turn away 15 young people in March due to a lack of available beds.
Now, Karinya Young Women Service treasurer Lisa Amerikanos is calling for a national housing plan to be included in the upcoming federal election campaign.
Ms Amerikanos said many young women have to stay at the shelter for longer periods because there are no medium-term options for a safe home.
"In turn, Karinya's resources are under increased pressure, despite offering callbacks and working collaboratively with other services," she said.
The specialist homelessness provider, which offers emergency short-term accommodation, improves the lives of young women by providing a safe space to build independence.
On Youth Homelessness Matters Day, on Wednesday, Karinya joined the national campaign to raise awareness and calls for a national housing plan.
The organisation is welcoming a discussion with candidates of all major political party to call for the "urgent" need for housing solutions in the state's North.
"The recent federal budget was heartbreaking, to see nothing for our most at-risk young people who just need safety and certainty," she said. "Increased support for younger people, aged 13 to 15, is critical."

Ms Amerikanos said low Youth Allowance payments, rents inflated by the housing crisis, insufficient supports for young people needing medium-term housing and a lack of employment pathways all contribute to youth homelessness.
"A lack of pathways from emergency accommodation into more stable options exacerbates those challenges," she said.
"A national plan which addresses regional deficits, such as the lack of medium-term options for young people in the state's North, will go some way to addressing the issues."
The Youth Network of Tasmania also called for a national plan on Wednesday.
The election will be held on May 18.
About 42 per cent of the nation's homeless are aged between 12 and 25. Despite these high numbers, there is no national plan to address youth homelessness in Australia, YNOT said.
Chief executive Tania Hunt said the issue needed to be addressed, with young people continually disproportionately represented in the homelessness population in Tasmania.
YNOT welcomed the recent release of the state government's Affordable Housing Action Plan 2019-2023 but said some young people were still being left behind.
