Trees outside the Australian Federal Police building, and CPP carparks on Murray Street, Royal Street, Queens Gardens, Point Fraser and Terrace Road were also wrapped in blue.

City of Perth Manager Parking Services Sandra Arnold said 10 staff were involved the transformation ahead of Mental Health Week.

The coloured trees let people in the CBD know “it’s ok to not be ok” and help break down the stigma associated with mental illness.

The initiative is part of the Blue Tree Project, designed to spark conversations and awareness of mental wellbeing. To date, 524 trees nationally have been painted blue under the project.

The City also organised trees along St George’s Terrace to be wrapped in blue fabric.

Ms Arnold said the parking team was contacted by the Australian Federal Police after realising this was an initiative the City of Perth Parking Team were looking at supporting.

Both teams decided the tree outside the AFP building was a great place to start.

Mental Health Week is held in Western Australia from October 10 to 17 and the temporary CPP installations will remain until October 23.
