An opposition push to topple Jacinta Allan has been slammed as the Victorian premier's predecessor makes a rare public appearance.
Opposition Leader Jess Wilson gave notice to state parliament's lower house on Thursday that the coalition would move a motion of no confidence in the premier and her ministers.
Only one motion of no confidence can be moved each four-year term and can lead to the dissolution of parliament if passed, well before the scheduled state election on November 28.
Ms Wilson said there must be accountability for government failings, citing record crime, skyrocketing net debt, major project cost blowouts and delays, and the 2026 Commonwealth Games fiasco.
"We could bring forward the election - I know Victorians would want to see that," the state Liberal leader told reporters.
