Resource companies and union groups have emerged as the largest donors to political parties ahead of the Secret Harbour by-election [1].
These disclosures provide transparency into the financial interests influencing the race for the outer-suburban seat. The funding patterns highlight the traditional divide between corporate resource interests and organized labor in Western Australian politics.
The by-election was triggered by the resignation of Labor MP Paul Papalia in July 2026 [4]. The contest centers on the Secret Harbour electorate, located between Rockingham and Mandurah in Perth [2].
Under Western Australian electoral law, parties must report any donation within 24 hours of receipt [3]. This mandatory reporting requirement has forced a rapid public accounting of who is financing the campaigns since the election was called this month [2].
While resource giants and union groups have provided significant funding to major parties [1], other participants show different patterns. One Nation WA has disclosed only one major donor since the by-election was called [3]. This stands in contrast to the broader influx of capital from industry and labor groups supporting the primary contenders [1].
The parties, including Labor, Liberal, National, and One Nation WA, are utilizing these funds to run campaign activities across the electorate [1]. The high volume of reporting is a direct result of the state's strict disclosure timeline, which aims to prevent secret funding from influencing voters immediately before a poll [3].
“Resource companies and union groups have emerged as the largest donors.”
The dominance of resource companies and unions in the funding pool suggests that the Secret Harbour by-election will likely be a proxy battle over economic policy and industry regulation. Because Western Australian law requires near-instant disclosure, voters can see in real-time which interest groups are betting on specific candidates, reducing the impact of 'dark money' typically seen in later stages of political campaigns.
