MONDAY’S storms washed away half the sand trucked in over summer at a beach north of Hillarys Boat Harbour.

But Joondalup Mayor Albert Jacob said moving the sand from Sorrento beach had protected the Hillarys dunes.

“The storms caused some erosion at Hillarys Beach Park,” he said.

“About half of the sand transported from Sorrento Beach late last year was displaced by storm activities in the last few days. However, the sand that was transported did protect the dune systems.”

• Bringing in sand at north coast beaches also helped prevent further erosion in the storms.

The City of Wanneroo placed about 2500 tonnes at Yanchep Lagoon near the start of the month between the new and old surf life saving clubs.

This week it has been doing works at Quinns Dog Beach, including the placement of about 3500 tonnes of sand next to Queenscliff Park and the northern rock groyne.

The annual work at Quinns aims to prevent erosion and damage to coastal infrastructure and dunes.

The City said loss of sand during high tides over winter was expected and would be monitored during and after storms.

Additional works would be done as required to make the beach safe and functional before summer.
