The shortlist of sites for a new public high school in Perth's western suburbs has been released.

WA Education Minister Peter Collier says the Government is looking at the former City Beach High School site (currently leased by the International School of WA), vacant land at Fred Burton Park, and also in City Beach.

Vacant land on the corner of The Boulevard and West Coast Highway in City Beach and vacant land in Mount Claremont (on the corner of Rochdale and Wollaston roads) are possible locations too.

City Beach High School was closed due to declining student numbers in 2005, while former schools Hollywood High and Swanbourne High closed in 2000.

This has left nearby high schools increasingly crowded, with Churchlands Senior High School having to enrol more than 2,300 students this year.

Shenton College has close to 1,900 students, while Mount Lawley Senior High School serves 1,500.

The new school is set to accommodate 2,000 students when it opens in 2019.

But no Government funds have been allocated, leading Mr Collier to suggest a public-private partnership (PPP) could be involved.

“The PPP model at this stage is going to save the Government money and the PPP model is very, very productive in terms of the fact it does what principals want, it leaves the maintenance of their schools to someone else,” he said.

“The school itself is part of a multifaceted approach - we are also increasing the capacity in Mount Lawley [Senior High School] and Shenton [College].”

Opposition education spokeswoman Sue Ellery told the ABC that the Government was taking its time.

“Ten months after he announced planning was well underway, I would have expected today's announcement to be the site,” she said.

“We know that under proper planning to keep up abreast of the growing population, the Government needs to factor in money to build six new primary schools a year.

“The last two budgets, this Government has allocated money for four. No wonder the system is under pressure.”
