COTA SA is creating new images and expectations of our older years... boldly reframing the way we age. Our Vision: Ageing in Australia is a time of possibility, opportunity and influence. Our Mission: We advance the rights, interests and futures of Australians as we age. COTA SA is the peak body for 633,000 older people in South Australia. We provide a platform to ensure that older South Australians are part of decision-making by government and industry on everything from income and employment to housing and health.
