Regional Express (Rex) has posted a travel alert advising passengers to allow extra time at Sydney Airport’s Terminal 3 tomorrow (Thursday, 24 September) because of protected industrial action by security-screening contractors. The carrier, which operates the bulk of its services from T3, said the announcement was updated at 4:05 pm AEST on 23 September and flags two peak disruption windows: 7:30-9:30 am and 6:00-8:00 pm. Although Rex issued the alert, the walk-offs will affect all airlines that rely on Terminal 3’s screening channels—including Qantas domestic services—potentially lengthening queues for thousands of business travellers shuttling between Sydney, Melbourne and Brisbane. The airport has not announced flight cancellations, but travellers failing to clear security in time risk missing departures during the busy Thursday corporate-travel wave. For employers, the short-notice stoppage highlights the need for proactive communication with travelling staff and the value of mobile traveller-tracking tools that can push real-time airport advisories. Companies with day-return meeting schedules should consider re-booking onto mid-day flights or arranging virtual options to avoid the morning peak. The action underscores wider labour-relations strains in Australia’s aviation security sector, where unions have been seeking wage rises to match rising living costs. Mobility programme owners may wish to build additional buffers into itineraries for the remainder of 2026 while further negotiations are under way.
