Australia’s Nationals have formally split from the Liberal-National Coalition, ending a federal partnership that had endured in one form or another since 1987 and leaving the country’s conservative opposition divided after a bruising election defeat.
The decision was announced after talks at Parliament House on Tuesday and followed a breakdown in negotiations with Liberal leader Sussan Ley. Nationals leader David Littleproud said the party would not enter a new coalition agreement with the Liberals. He pointed to a set of policy disputes that the Nationals wanted locked into place before any renewed arrangement.
Among the sticking points were nuclear policy, a proposed $20 billion regional Australia future fund, powers to force break-ups in the supermarket sector and minimum standards for communications services in regional areas. The Nationals also wanted shadow ministers to retain the right to vote against opposition policy in parliament, a demand the Liberals regarded as incompatible with the discipline expected of a shared frontbench.
Ley described the split as disappointing but said the Liberal party would continue to work constructively with the Nationals. She also said the Liberal door remained open if the Nationals wanted to rejoin before the next election. Still, she confirmed that the Liberals would move ahead with a Liberal-only shadow ministry and a separate policy review process.
The rupture comes after Labor won the 3 May election decisively and left the Coalition reeling. The Guardian report in the packet says the Liberals are expected to hold only 28 lower house seats while the Nationals have 15, a result that has intensified questions about the future of the opposition alliance.
Littleproud framed the decision as a principled move rather than a permanent divorce. He said the Nationals wanted to preserve hard-fought regional gains and to develop their own policy positions. He also left the door open to a future reunion, though without any guarantee.
The split is historically significant because the Coalition has broken apart only a handful of times in federal politics. It has also exposed a deeper argument about what a modern conservative opposition should look like after a poor result in the cities and growing disagreement over climate and regional development.
That argument is being watched closely because the Liberals and Nationals do not merely share voters; they have long shared the mechanics of opposition in Canberra. A separate Nationals bench and separate policy line mean a more complicated parliament, even if both parties continue to oppose Labor.
The event date is 2025-05-20. The essential facts on that date were the formal split, the policy disagreements that drove it, and the leadership decisions that followed.
That leaves the opposition with a practical problem as well as a political one. A split coalition means a weaker shared message, separate frontbench arrangements and less certainty about which side of the old alliance will define the opposition brand for the next election cycle. Even if the parties continue to coordinate on some issues, the formal breakup means every policy fight will now be managed through more distance and less discipline than before.
