Some of Sydney’s fast-growing suburbs will get 15 new public schools as part of a $3.5 billion education boost to be unveiled in the NSW budget this month.

The state government said the new funding would result in more than 60 facilities either built or upgraded in Sydney’s west and southwest over the next four years.

“This is important for the fastest growing part of the country,” Mr Minns told 2GB radio on Monday.

“We’re investing particularly in southwestern Sydney – new high schools, new primary schools. This is where families are moving to.”

Mr Minns said the population in some suburbs had increased by up to 8000 people in recent years but no new schools had been built.

“The independent schools are in there, we’re going to put public schools (in),” the premier said.

The government said new primary school would be located near Sydney Olympic Park, Gables, Melonba, Tallawong, Gregory Hills, Nirimba Fields and Liverpool.

New high schools would be situated at Wentworth Point, Melrose Park, Melonba, Schofields and Tallawong, Jordan Springs, Gledswood Hills and Gregory Hills, Leppington and Denham Court, and Edmondson Park.

The funding would give the area quality public schools after the coalition failed to provide local essential services, the government said.

Opposition education spokesperson Sarah Mitchell has been contacted for comment.

The multibillion-dollar promise comes despite the government being under pressure to curb spending after admitting it faced about $7 billion in budget pain-points in the next four years.
