Voting opens in the Western Australian Secret Harbour byelection, with more than a thousand voters casting ballots early, according to reports from multiple outlets.

The coverage is consistent across the Sydney Morning Herald, The Age, and the Brisbane Times on the early-voting figure and the location. However, none of the provided summaries includes details beyond the start of early polling, such as the reason for the byelection, candidates involved, or polling day timing. As a result, the emphasis in the available material remains on the commencement of voting and the initial turnout during the early period.
