Dan and Dom: the two premiers leading a vibe shift in Australian politics

So far, they have been successful.

The differences between Andrews and Perrottet are part of their success. Their partnership blunts any political attacks at a state level and at a federal level it allows them more bargaining power.

When the leaders of the two most populous states come together, Albanese is forced to listen. And, in the spirit of consensus, so far he has.

The partnership also provides a new opportunity for two old governments, Robinson said. Andrews is seeking a third term, while the Coalition in NSW is seeking a fourth.

A senior Victorian Labor source says they are aware of the challenges involved with securing another term. They say the federal and South Australian elections had proved incumbent governments cannot rest on their records.

In an interview with Guardian Australia, Andrews revealed he first reached out to Perrottet in October last year when the then NSW treasurer replaced Gladys Berejiklian as premier, at the urging of former prime minister Paul Keating.

Voters will be watching to see what they tackle together next.
