Multiple outlets report that Sydney Airport experiences operational issues affecting some flights, but Perth-to-Sydney services are not delayed. The West Australian and PerthNow both say that while nearly 100 domestic or international flights departing from Sydney have been delayed or cancelled, flights traveling between Perth and Sydney continue to operate without delays. The reports indicate that the disruption is concentrated among services originating at Sydney, rather than impacting inbound routes from Perth. Both sources describe the same overall scale of the disruption—close to 100 services affected—while reaching the same conclusion for Perth–Sydney flights. No additional details about the cause of the issues are provided in the supplied summaries, and there are no claims of changes to timetables for Perth–Sydney flights. Overall, the coverage focuses on the contrast between broad delays and cancellations at Sydney and the absence of delays for flights on the Perth–Sydney route.
