Sydney gets a second international gateway on 25 October, when Western Sydney International Nancy-Bird Walton Airport (WSI) starts taking passengers. Named after Australia's first female commercial pilot, the airport has been seven years in the making and is designed to ease the strain on Kingsford Smith, the city's existing airport, which operates under a night curfew and is running out of capacity. WSI's 3.7 km runway allows 24-hour flying, and long-term plans could see it handle up to 82 million passengers a year — which would eventually make it Australia's busiest gateway.
The launch route map fills up fast. Jetstar starts domestic flights to Melbourne, Brisbane and the Gold Coast, and Air New Zealand operates the first international service, to Auckland, on 26 October. Singapore Airlines follows with daily Singapore flights from 23 November — handy for UK and European travellers connecting through Changi. Vietjet Air adds Ho Chi Minh City in January 2027, and Fiji Airways starts flying to Nadi in March.
Are fares actually cheaper? Partly. The Guardian compared December prices and found Jetstar returns to Melbourne from A$187 at WSI versus A$258 from Kingsford Smith, with Gold Coast flights also cheaper. Brisbane was more competitive from the old airport, and most international fares still favour Kingsford Smith — though Fiji Airways offers potential savings to Nadi from the west.
Getting there is the catch. The airport sits more than 60 km from the city centre, roughly an hour's drive versus 20 minutes to Kingsford Smith. Until the new metro line opens, a free shuttle runs every 30 minutes to St Marys railway station, and an on-demand electric Super Shuttle links Parramatta, the Sydney CBD and Kingsford Smith. Taxis and ride-hailing from central Sydney will add real money to a budget fare. On the plus side, the 6,000-space car park is significantly cheaper than Kingsford Smith parking while introductory discounts last.
There's a premium play too: an 80-seat lounge designed by COX Architecture opens in November, initially for Singapore Airlines passengers, with an open kitchen, bar, shower suites and Blue Mountains views, expanding to 130 seats later.
Who should care? Anyone flying budget routes up and down Australia's east coast, travellers to Fiji or New Zealand, and — crucially — people staying in Sydney's west. WSI puts you far closer to the Blue Mountains, Featherdale Wildlife Park, Liverpool and Campbelltown, so if that's your trip, the long transfer into the city is irrelevant. The project is also a big deal locally, having already generated over 12,800 construction jobs and more than A$500 million of investment across some 360 Western Sydney businesses. Compare total costs — fare plus transfer plus parking — and the cheap tickets can be genuinely cheap.
