On April 28, the council unanimously agreed to extend a trial approved last December for another 12 months, and to add courts in Yanchep, Butler, Banksia Grove, Wanneroo and Girrawheen.
A staff report to the council said a time-lapse camera at the Bellport Tennis Courts in Mindarie recorded usage patterns between February 17 and March 4, after signs went up and residents received notification of the trial.
"The courts were utilised every day, with average visits on weekdays by up to 20 individuals and over the weekend up to 35 individuals," it said.

Councillor Sabine Winton said the trial had been "an overwhelming success" and there had been "no vandalism or conflicts amongst the different users".
Cr Winton said the trial program sat well with the City's Your Move project that encouraged residents to get active.
The Koondoola Park courts were also part of the trial, but the report said resurfacing finished in March, so data was only collected between April 20 and May 3.
Cr Domenic Zappa said many south ward residents had been using the Koondoola courts since it was resurfaced.
Fees will still apply at courts used by tennis clubs: Gumblossom Park (Quinns Rocks), Elliot Road (Wanneroo) and Montrose Park (Girrawheen).
