St Patricks Soccer Club will be booted out of its sixth home in 36 years at the end of the season.
Currently based at Anne Aquilina Reserve in Rooty Hill, the ground has become a part of an expanded Blacktown International Sportspark to be used for "elite sport".
The club has been working with Blacktown Council for 18 months to try to find a new home.
Councillors voted last week to move a motion which will see the 400-member club move to Bert Saunders Reserve in Doonside "as soon as practicably possible", subject to community consultation.
The club was previously told by the council it was unsafe for a family sporting organisation.
Club officials say the ground's fields and amenities are inadequate in their present condition.
"Moving was inevitable, which we didn't have a problem with," club president Keiran Pender said.
"It's the fact the council refused to make allowances. All we ask is access to fields and amenities equitable to what we have now, which won't be the case."
The club's future has been in limbo since 2012 when officials were told it had to relocate.
It was effectively allowed to stay in 2013 and again this year after residents raised concerns about a proposed move to Harvey Park in Marayong, which St Pat's would share with another club.
The club's access to Anne Aquilina fields have halved from four in 2012 to two this season.
"We play 32 games on a weekend and have training four nights a week," Mr Pender said.
"We also provide a service to the school community and open the canteen for them. The referees will take one look at the Bert Saunders Reserve fields and say they're not up to standard."
The club now asks no decision be made on its relocation until the council finalises contract negotiations with A-League club Western Sydney Wanderers.
"All we're asking is for St Pat's be part of the plan for a proper home," club secretary Silvana Martignago said.
