The walk is used to raise money for blood cancer research, with families, friends and colleagues gathering to shine lanterns of hope.
Gold lanterns are used to remember loved ones, while blue signifies support for others.
Therese Weldt will be one of many shining a white lantern to reflect on their own journey with the disease.
The Hamilton Hill resident was diagnosed with lymphoblastic leukaemia when she was 10, but has now been free of a relapse for 15 years.
Ms Weldt previously worked in parasitology research and for six months on a cancer project with the WA Institute for Medical Research.
She now works as a registered nurse and fundraises whenever she can.
‘Blood cancer research is quite important to me. Having worked in medical research, I know (how much) effort and dedication goes into it. It’s important to have the WA community’s support behind it,’ she said.
