Oceans 2 Earth Volunteers (O2E) was founded by sisters Cassie Smith and Tracy Leske, who shared a vision of ethical travel that prioritises conservation over commercial gain. Inspired by their experiences in wildlife rescue and environmental advocacy, they set out to create volunteer programs where participants could directly contribute to meaningful causes. Since 2010, O2E has been connecting people from all walks of life with grassroots conservationists and wildlife carers, fostering real change for our planet.
