Butterfly notes and flowers will be available to be placed in the water, as a tribute to the attendees late children.
A light breakfast will also be provided for a gold coin donation.
The Compassionate Friends provide support and help individuals and families understand the grieving process.
In a previous interview with the Mandurah Mail, founding member of Mandurah TCF, Margot McAllister, referred to the grief associated with losing a child as "complicated".
"It's not meant to work that way. Parents are supposed to die before their children," she said.
"It is not the usual sequence of events."
Ms McAllister said the group provided an essential support service within the community.
"Knowing everyone else here has lost a child - it helps to normalise it and do away with the loneliness and alienation," she said.
"We help people grieve in a healthy way."
