Can anyone confirm this.
In the event the Victorian government is unable to complete it's four year fix term, (because of loss of confidence or losses in by-elections). The earlier than usual general election will only be for three years not four.
That's correct. If an election were to be held early, the next election will return to the last Saturday in November, but the term of that parliament between those two elections will not extend beyond four years, so it's end will be brought forward a year.
