The 1906 Toorak state by-election was held on 10 October 1906 to elect the next member for Toorak in the Victorian Legislative Assembly, following the resignation of incumbent MP George Fairbairn.
Fairbairn resigned to contest the newly created seat of Fawkner in the Australian House of Representatives at the 1906 federal election.
The by-election was won by Independent Ministerialist candidate Norman Bayles, although he later joined the Ministerialists.[1]
