All West Australian police officers on duty will carry guns at the Kings Park Anzac service tomorrow morning.

WA Police Union President George Tilbury said the extra security measures were a result of the recent terror raids in Melbourne.

“This unprecedented move is in line with the alarming terror raids in Melbourne and heightened terrorism alert for police officers in Australia,” Mr Tilbury said.

Mr Tilbury said the union supported the directive from WA Police that officers who attended the Anzac Day events would be armed at all times.

“Police officers vigorously defend our Australian way of life and we will not let terrorists diminish or destroy this,” he said.

Mr Tilbury said he encouraged the community to attend Anzac services in support of those who gave their lives to defend our nation.

Returned and Services League state president Graham Edwards said the RSL has put plenty of planning and work into providing services at more than 100 locations around WA.

“I would encourage people to take advantage of the good weather and long weekend and to turn out in large numbers in this very special year of the Anzac centenary,” Mr Edwards said.

RSL media officer John Arthur said  the day would have many highlights.

“There will be a release of 1023 balloons representing the lives of the West Australians that died at Gallipoli,” Mr Arthur said.

The dawn service will be held at Kings Park at 5am tomorrow.
