"Talking about Black Saturday can be very difficult for some but talking can be the best healer," Ms Leadbeater said.
"Sometimes, just giving people an opportunity to feel heard is enough to make a big difference."
Dr Gordon advised people to make a plan about how they wanted to reflect and commemorate the tragedy.
"It will give you a greater sense of control, it will give you a sense of history, of survival," he said.
"Some people might like to come down to the official process, other people might like to go to the local event, other people might like to just have a barbecue in the backyard with close friends - that's fine, everything's right."
Ms Leadbeater led the recovery effort for the Kinglake Ranges in 2009 and now supports national policy development and training for emergency management staff and volunteers.
Dr Gordon is a consultant to the Victorian government and the Red Cross and has worked with communities after Ash Wednesday, the Port Arthur shooting, the Bali Bombings, Black Saturday and the Christchurch earthquake.
