Discarded needles put kids at risk at Calista park.

Megan Doble said she was constantly finding needles in the playground, even needles pointing upwards at the base of the slide.

“I have found three fit packs in the past few months,” she said.

“I’ve found heaps of clipseal bags.

“It’s getting worse.”

Ms Doble said she would sweep the sandpit with her boots before allowing her sons, aged one, four and eight, to play on the equipment.

Wellard grandmother Elizabeth Padovan said she was concerned for her grandchildren playing at the park.

“They need signs warning parents about the dangers,” she said.

“They should get rid of the sand and replace it with rubber matting.”

The women were also concerned about at least one homeless person living in the public toilets at the park.

Kwinana Mayor Carol Adams said the council took the reports very seriously.

“We ask members of the public to instantly report any needle sightings via a phone call to the City with the exact location and contact details,” she said.

“Our team is quick to respond to these calls as a matter of urgency and we also do regular scheduled maintenance of the parks, which includes checking the area and raking the sand for debris.

“All of our parks have scheduled upgrades in the coming years where the ability to replace sand with soft fall will be assessed on a case-by-case basis as these take place.”
