This year marks 50 years since the launch of one of Australia’s first major conservation battles, waged against Queensland’s ultra-conservative, pro-development premier Joh Bjelke-Petersen. It was for a location few had ever heard of – Cooloola, an area that stretches from Noosa to Rainbow Beach, around 70 km north. The unlikely leader of this campaign was a wildflower painter named Kathleen McArthur, who led the Caloundra branch of an environmental group the Australian newspaper called “the most militant of conservation cells”. Kathleen, together with colleagues such as poet Judith Wright, pioneered and honed activist strategies that are still instructive today. She understood art’s ability to prompt human emotion and marshal the public support required to bring about change.
