John Ruddick

Libertarian Party Ruddick left the Liberal Party to join the Liberal Democrats (renamed in 2024 to the Libertarian Party) in 2021, following public dissatisfaction with the Liberals' response to COVID-19, lockdowns and what he alleged to be a lack of democratisation in the party.

In late 2022, the Liberal Democrats NSW state executive voted to disendorse Ruddick as its lead MLC candidate for the NSW state election following allegations of bullying and harassment of campaign staff, allegations which Ruddick denied. After a petition calling for a special general meeting over the matter was signed by over 25% of the party's 320 members, Ruddick was re-endorsed.

The party received 3.53% of the primary vote in the upper house ballot, a swing of +1.3%, a quota of 0.7755. His term will expire on 7 March 2031.
