Bright flash reported in the sky across Sydney by multiple residents

Reports from multiple outlets say residents across Sydney see a bright flash in the sky. The accounts describe a sudden, intense flash observed by people in different parts of the city. The reports are based on public observations from readers and viewers rather than any confirmed official assessment of the cause. At the time of reporting, there is no shared, specific explanation in the provided summaries, and the flash is presented as an unusual event prompting public attention. None of the supplied articles include details such as duration, exact location, movement, color, accompanying sound, or whether authorities have investigated or released a statement. The coverage therefore focuses on the fact that multiple people independently report seeing the same kind of phenomenon over Sydney. The event is treated as a developing incident until further information is available.
