Both W Tree and nearby Gillingal Post Offices opened around 1902. Gillingal closed in 1938; W Tree was reduced to a telegraph office in 1921 and closed in 1969. Many people think that W Tree has only been settled since the mid-1970s, when Fred Koch had an idea of forming a community of like-minded people and bought 800ha of land.
Hodge family
Some of the original inhabitants of W Tree were the Hodges, among them Henry Hodge and his second wife Mary, who moved from the Meredith district and settled at Murrundella in the early 1900s. Henry had 3 children with his first wife Elizabeth, and a further 14 children with Mary. Their tenth child was Leomin Hodge who was born on 20 May 1904. Leo was educated at the original W Tree State School. He went to the school for 4 years, and left school aged fourteen to work on the family farm. In 1939 he and his wife Joyce purchased a property at W Tree called The Cottage, which they later renamed Poorinda, an aboriginal name for "light". Leo farmed Merino sheep and Hereford cattle on his land, as well as working for the Lands Department as a dingo trapper. He had many interests including painting and playing violin, but he is most remembered for breeding and developing the "Poorinda" grevilleas, many of which are still available today. Leo became interested in breeding grevilleas after finding seedlings in his garden. His first trials involved crossing G. juniperina with G. victoriae and G. 'Poorinda Queen' was bred in 1952, followed by many more. He did not have any formal horticultural training and was self-taught, but hosted hundreds of visitors including many noted plant naturalists and botanists. "Poorinda" the home no longer exists, it eventually became part of the ONTOS property and burnt to the ground in the late 1990s. The land where the house stood is now owned by Ian and Julia Delaney and was the venue for the 2009 W Tree Spirit of Place Festival.
Festivals
Every year since 2008 takes place the W Tree Spirit of Place celebration. For 2009 the theme of the celebration is to formally establish the W Tree community's custodianship of the Detarka Park reserve through a creative ritual involving a spectacular performance, at night, amongst the giant forest trees.
