Victorian Liberal Party member and education think tank director Colleen Harkin quits the Liberal Party a week after attending a One Nation fundraiser in Melbourne. Both reports describe Harkin’s departure as linked to her public engagement with One Nation, including praise for the party. The West Australian frames her move as a significant defection that adds to pressure on the Liberal Party, while ABC Australia focuses on the immediate timeline, noting she leaves the major party shortly after the event. Neither source provides details of any formal joining process or specific policy positions beyond Harkin’s praise and participation in One Nation-related activities. The reporting also indicates Harkin is a comparatively high-profile figure within the Liberal Party, based on her role as an education director for a think tank and her visibility in Victorian Liberal circles. Overall, the sources agree that Harkin resigns from the Liberal Party following participation in a One Nation fundraiser and related praise, marking her as a new figure associated with One Nation.
