The party’s leader, Ellen Sandell, lambasted Labor’s decision on Tuesday to run an open ticket in Prahran, an inner Melbourne seat currently held by the Liberals’ Rachel Westaway on a tiny 1.3% margin.

It means Labor’s how-to-vote material will encourage voters to place their candidate, Meghan Hopper, first on the ballot but will not direct them how to allocate their remaining preferences. Instead, the remaining boxes on its how-to-vote material will probably remain blank.

Labor preferences are key to the Greens cinching back the seat, which they lost in a 2025 byelection.
