New data released by the Australian Electoral Commission reveals the funding sources for political parties in the lead-up to the 2025 federal election, providing voters with insight into which industries and donors are backing each side of politics.The disclosures - required under electoral law but often delayed and difficult to parse - show the familiar pattern of resource companies favouring the Coalition, while unions back Labor. But the devil is in the details.Mining interests remain major donors to both major parties, though the Coalition receives significantly more. Property developers, gambling companies, and pharmaceutical interests also feature prominently across the board.The Greens, who have positioned themselves against corporate donations, receive the bulk of their funding from individual donors and public campaign financing - though they've faced criticism for accepting donations from some wealthy individuals with business interests.One Nation and other minor parties showed significant funding from sources that remain obscure due to loopholes in disclosure requirements."These disclosures should help voters understand whose interests each party serves," said one democracy advocate. "But our disclosure laws are so weak that much remains hidden. We only see donations above the threshold, and even then only after significant delays."Calls for real-time donation disclosure and lower thresholds have been rejected by both major parties, who benefit from the current opacity.The full data is available on the AEC website for those with the patience to wade through thousands of pages of filings.
