The Channel Seven Perth Telethon, known simply as Telethon, is an annual telethon established in 1968 by philanthropist Sir James Cruthers and produced by TVW, a Seven Network-owned television station in Perth, Western Australia for two main beneficiaries—Princess Margaret Hospital for Children and the Telethon Kids Instituteplus many other beneficiaries including the Telethon Speech & Hearing Centre. Telethon's CEO, Steve Mummery, has called it "the highest donating Telethon (per capita) in the world", with it surpassing A$100 million in total donations in 2010, and $200 million in 2015.
The Channel 7 Telethon Trust is the charitable trust behind the event and its related fundraising activities. The philosophy behind the Channel 7 Telethon Trusts to financially support the medical and social welfare of children and young people and to fund research into children's diseases.
The event usually runs around 26 hours non-stop, from 6.30pm on a Saturday night in October, broadcasting live across Western Australia on TVW7 throughout the metropolitan area of Perth and the Golden West Network (GWN7) across the rest of Western Australia (Australia's biggest state by area), and since 2005 has been held at the Perth Convention and Exhibition Centre. The event aims to raise money for its beneficiaries from donations from private citizens and corporations, as well as from special fundraising events held throughout the year and the public auction of two specially built Telethon homes—one in the metropolitan area of Perth and one in the regional area of Western Australia.
Each year, there are also two children (one from the metropolitan area and one from a regional area) who have had reason to be a patient at Princess Margaret Hospital over the past twelve months. Over the Telethon weekend, these two children are chosen to represent all children who benefit from the money raised. From 2010, these two children have been referred to as the "Little Telethon Stars".
