⬜ Under redrawn boundaries, Labor expected to start favourite in new seats in ACT and Victoria, giving it a two-seat head start.

⬜ It is the first major electoral test for Prime Minister Scott Morrison. Last one in 2016 ended in a one-seat majority for the coalition under Malcolm Turnbull.

⬜ Bill Shorten is longest serving opposition leader since Kim Beazley. His seat of Maribyrnong has been made more marginal due to boundary changes.

⬜ Minor parties will find it harder to win or retain seats as there is a higher vote quota in the Senate than during the double-dissolution election.
