The Old Butter Factory Museum treasurer Nola Angus encouraged the community to join the occasion.
“The Old Butter Factory is so unique and iconic, Busselton is very lucky to have such a historical building,” she said.
“The anniversary event is about appreciating where we have come from and where Busselton has come from.”
