New South Wales Labor Party

The New South Wales Labor Party, officially known as the Australian Labor Party (New South Wales Branch) and commonly referred to simply as NSW Labor, is the New South Wales branch of the Australian Labor Party (ALP). The branch is the current ruling party in the state of New South Wales and is led by Chris Minns, who has served concurrently as premier of New South Wales since 2023.

The parliamentary leader is elected from and by the members of the party caucus, comprising all party members in the Legislative Assembly and Legislative Council. The party factions have a strong influence on the election of the leader. The leader's position is dependent on the continuing support of the caucus (and party factions) and the leader may be deposed by failing to win a vote of confidence of parliamentary members. By convention, the premier sits in the Legislative Assembly, and is the leader of the party controlling a majority in that house. The party leader also typically is a member of the Assembly, though this is not a strict party constitutional requirement. Barrie Unsworth, for example, was elected party leader while a member of the Legislative Council. He then transferred to the Assembly by winning a seat at a by-election.

When the Labor party wins sufficient seats to be able to control a majority in the Legislative Assembly, the party leader becomes the State Premier and Labor will form the government. When Labor is the largest party not in government, the party leader becomes the Leader of the Opposition. To become a premier or opposition leader, the party leader must be or within a short period of time become a member of the Legislative Assembly.
