A new report has ranked Australia’s worst-performing domestic and international flight routes.
Travellers flying out of Darwin may want to build some extra buffer into their itineraries. New research has revealed the most delayed flight routes in Australia, with some services arriving nearly an hour late on average – and the Northern Territory capital features three times in the top 10.
The Delay to Departure Report , published by business communications platform Esendex Australia, analysed hundreds of domestic and international routes from Australia’s busiest airports over the past year, using Flightradar24 data to compare scheduled versus actual arrival times.

Darwin – Groote Eylandt: 46 minutes
Alice Springs – Perth: 37 minutes

On international routes, Brisbane to Port Moresby, Papua New Guinea takes the top spot with an average 27-minute delay – followed by Melbourne to Delhi at 25 minutes. Melbourne features three times on the international list in total. The most delayed international departures from Australia are:
Brisbane – Port Moresby, Papua New Guinea: 27 minutes
Melbourne – Delhi, India: 25 minutes
Perth – Tansonnhat, Vietnam / Sydney – Christchurch, New Zealand: 19 minutes
Perth – Kuala Lumpur, Malaysia / Brisbane – Honiara, Solomon Islands: 18 minutes
Melbourne – Los Angeles, USA / Melbourne – Colombo, Sri Lanka: 15 minutes
Jonathan Walsh, General Manager at Esendex Australia, said the downstream impact of delays is often underestimated.
“Delayed flights can have a real knock-on effect for travellers, particularly on routes where people are relying on onward connections, ground transport, or tight schedules at the other end," he said.
“Disruption is often unavoidable, but how that disruption is communicated makes a significant difference. Clear, timely updates help travellers make informed decisions, reducing stress and regaining a sense of control when plans change."
The report analysed 185 domestic routes across Australia’s major airports, plus 80 international routes from the country’s four busiest airports. On-time performance was measured against a 15-minute threshold. Data is current as of January 2026.

Where to drink & dine
1. The Bar
Indulge in the Fullerton Signature Afternoon Tea.
Inside The Fullerton Hotel Sydney’s lobby, The Bar does more than sling a few delicious cocktails (although it certainly does that well). Its brown leather chairs and glass ceiling create the perfect, almost al fresco, setting for the Fullerton Signature Afternoon Tea .
Served daily from 12 to 4 pm, the afternoon tea is a nod to the cherished social occasion it once was during the Victorian Renaissance era. People like to dress up for this afternoon tea, and if you’re lucky, a pianist often sits down at the on-site grand piano, just adding to the elegance.
The afternoon tea is served high tea style, offering reimagined British flavours of the Victorian Renaissance era with a unique blend of Australia’s culinary heritage. A sweet layer offers delights like a Malted Milk Envelope (a milk mousse layered between two biscuits), Bakewell Pudding (a super tasty egg-based pudding), and Apple Charlotte.
On the savoury layer, expect finger sandwiches with fillings like cucumber, egg and smoked salmon. While classic pinwheels and stuffed eggs almost make the menu. And, of course, all finished off with traditional scones served with cream and mixed berry jam.
Can’t fit in a whole afternoon tea? Be sure to at least order a slice of the 32-layered chocolate cake, a decadent mix of dark chocolate crémeux, fresh whipped cream, and Valrhona Azélia chocolate sauce.
2. The Place
Dine in the stunning GPO atrium.
On level one of The Fullerton Hotel Sydney lives The Place – the hotel’s restaurant, in an atrium overlooking the former GPO. Here, dine on Modern Australian cuisine – think fresh, local seafood and a Riverina steak sandwich – along with a touch of Singaporean signature dishes, like Thai-style green curry or chicken satay. All in the shadow of the GPO clock tower, enjoying the GPO atrium’s natural light.
