The day was initiated by two young Australian students in response to a growing number of media reports of teenage suicides linked to homophobic bullying.

The NSW Police Force had been actively involved in supporting the event since 2012 through a series of school visits, presentations, community activities and on social media.

Local police officers will have a stall at Orana Mall to promote Wear It Purple Day on August 29.

The theme for the day will be Don't Box Me In, meaning everyone had the right to be proud of who they were and to live without labels or judgment.

"The message of acceptance and equality that Wear it Purple Day conveys is critical," NSWPF Corporate Sponsor for Sexuality and Gender Diversity, Superintendent Tony Crandell said. "Police have a responsibility to work with communities to ensure they feel supported, safe and free from harassment, bullying and violence.

"Most people dislike being judged and boxed in, and the idea that no matter who we are, we have the right to be proud, safe and secure is something we, as an organisation, strongly advocate for.

"Police should have an active role in education and support to ensure that right."

Orana LAC Inspector Gemini Bakos said promotional giveaways would be available at the information stall.

"Police officers should be seen as trusted community members," she said.

"They can make a real difference in the lives of young people experiencing homophobic bullying.

"Look out for police on the day distributing information and promotional materials to raise awareness and support diversity."
