At the 1901 general election, Wood was defeated in West Perth by George Leake, who succeeded George Throssell as premier just over a month later. He attempted to re-enter parliament at the 1901 West Kimberley by-election, but lost to Sydney Pigott.[3] In 1902, Wood was elected to the Legislative Council, defeating James Speed in Metropolitan-Suburban Province. He served until his sudden death in August 1903, which occurred while on a holiday to Mandurah. He had been walking back to his lodgings from a day at the beach when he collapsed on the roadside (presumably due to heart failure), and his body was not found until the following morning.[4] Wood had married Mary Louisa Whitfield in 1879, with whom he had four children. One of his sons, Garnet Wood, was also a member of parliament, and also died in office.[2]
