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 said a time-lapse camera at Bellport Tennis Courts in Mindarie recorded usage between February 17 and March 4, after signs went up and residents received notification of the trial.
The courts were used every day, with average visits on weekdays by up to 20 people and over the weekend, up to 35, it said.
Altogether, 405 people used it during the trial period, although the report said that probably included repeat visitors.
Councillor Sabine Winton said the trial had been �an overwhelming success� and there had been �no vandalism or conflicts among the different users�.
Cr Winton said the trial program sat well with the City�s Your Move project that encouraged residents to get active.
�Hopefully they will get out there and become tennis experts,� she said.
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 they were resurfaced.
Fees will still apply at courts used by tennis clubs: Gumblossom Park (Quinns Rocks), Elliot Road (Wanneroo) and Montrose Park (Girrawheen).
