The Channel 7 Telethon Trust is a registered charity dedicated to financially supporting the medical and social welfare of children and young people in WA and fund research into children's diseases. Since its inception, Telethon has raised over $80 million for the children of WA and provided much needed financial assistance to a significant number of children's charitable organisations, children's hospitals and research/medical facilities.

Throughout the year, the Telethon Office (in partnership with many of Perth's leading organisations), coordinates a wide range of fun-filled, fundraising events and promotions. The funds raised from these events and promotions are announced and celebrated each year during the Telethon Weekend in October. National and international celebrities are invited to participate in the Telethon Weekend appeal, a live 24-hour charity appeal held at the Perth Convention Exhibition Centre. The appeal is broadcast on Channel 7 Perth and GWN.
