2023 Warrandyte state by-election
The 2023 Warrandyte state by-election was held on 26 August 2023 to elect the next member for Warrandyte in the Victorian Legislative Assembly, following the resignation of Liberal MP Ryan Smith.

Background
The electoral district of Warrandyte was established in 1976 and has consistently been a safe seat for the Liberal Party except from 1982 to 1988 when it was held by Lou Hill of the Labor Party. According the 2021 Census, Warrandyte's median age is 43 with a weekly median household income of $2,134 while more than 37% of residents attaining a bachelor's degree or higher. The district is characterised by the southern banks of the Yarra River, rolling hills, lush greenery, and pockets of bushland.

Resignation of Ryan Smith
Ryan Smith was first elected at the 2006 Victorian state election, replacing long-serving member Phil Honeywood who had held the seat since the 1988 election. Smith would continue to keep Warrandyte as a safe Liberal seat barring the 2018 and 2022 elections where it became marginal following the successes of the Australian Labor Party. Smith retained the seat at the 2022 election with a two-party-preferred vote of 54.2%, a slight swing from the previous election where there was a swing of over 7 per cent against him. Following the election of John Pesutto as leader, he was dropped from the shadow cabinet, having been a shadow minister under Matthew Guy and Michael O'Brien.

Smith announced his retirement in May 2023 after 16 years in parliament, with effect from 7 July. Smith did not tell leader John Pesutto of his resignation, with Pesutto instead learning about it through the media. He said that he had “become increasingly uncomfortable with the growing negative tone of politics, both internally and more broadly,” generally interpreted as Smith’s disquiet over Pesutto’s handling of the Moira Deeming-related leadership tensions that embroiled the Victorian Liberal Party in early and mid-2023.
