Sussan Ley’s challenge as opposition leader is to keep her party united and ready to govern in the event that the government loses public favour. That is, they need to be a ready alternative government.
Voters evaluate governments on the basis of what they’ve done, but also what they promise to do next. Opposition parties start on the back foot, as governments have greater public visibility and can use public money to ingratiate themselves with voters. Ley is particularly up against it, with only 51 members in her party room and little public confidence the party has any chance of winning the next federal election.
Inevitably though, the money runs dry or the government’s mistakes start to pile up. That’s when an opposition needs to be in a credible position to persuade swinging voters that they are a better option than the government. This broadly involves three stages: establishing competence, offering an alternative vision of government, and surviving the campaign.
