Yes — Air India operates the only non-stop Delhi–Sydney service, flight AI302, on the Boeing 787 Dreamliner. As of 2026 the frequency has been temporarily reduced from daily to roughly four times a week (around 4–5/week) through August 2026, part of a wider Air India schedule rationalisation driven by record jet-fuel prices and closed airspaces. The service is still operating — just less often — so confirm the exact days for your dates. Every other carrier on this city pair routes with one stop.
For dates without a non-stop, or for lower fares, strong one-stop choices include Singapore Airlines via Singapore, Qantas via Singapore, Cathay Pacific via Hong Kong, Malaysia Airlines via Kuala Lumpur, Thai Airways via Bangkok, and Gulf carriers (Qatar via Doha, Singapore-bound combinations). Asian hubs usually give the shortest total journey (≈15–17 hours); Gulf routings are longer but sometimes cheaper. Compare them all in the FlightGPT search.
The non-stop covers about 10,400 km in roughly 12 hours on AI302, tracking south-east across the Bay of Bengal and Southeast Asia into Australian airspace. One-stop itineraries run 15–18 hours total including the layover. Sydney is well ahead of India — 4 hours 30 minutes in Australian winter and 5 hours 30 minutes in the southern summer (Sydney observes daylight saving from early October to early April).
Peak demand is the Australian summer / Christmas–January window and the mid-year Indian holiday season; fares ease in February–May and again in October–November. Because the non-stop is supply-constrained in 2026, book it as early as you can — 2–4 months ahead — if a direct flight matters to you. One-stop fares are more elastic and reward flexibility. We don't publish fixed prices; check live fares in the FlightGPT search for your travel dates.
This is a long, premium route, so realistic savings come from trade-offs: accept a one-stop via an Asian hub instead of the non-stop, fly mid-week, and avoid the December peak. Singapore Airlines, Malaysia Airlines and Cathay Pacific frequently run competitive sale fares ex-Delhi. If the non-stop is your priority, book early rather than waiting for a discount that the reduced 2026 capacity is unlikely to deliver. Set a fare alert and compare cabins, since premium-economy gaps can be small on sale.
Delhi departures use Terminal 3 (T3), the international terminal at IGI; Air India check-in is on rows D–F. In Sydney, Air India and other international flights arrive at Sydney Kingsford Smith Airport, Terminal 1 (T1). T1 connects to the city in about 13 minutes via the Airport Link train (note the separate station access fee). Allow extra time at Sydney for Australia's strict biosecurity declarations on arrival.
Air India economy to Australia typically allows a generous 2 × 23 kg checked + 8 kg cabin, with more in premium economy and business. One-stop carriers vary: Singapore Airlines and Cathay Pacific usually offer 30 kg+ in economy on this long-haul market, while some Gulf fares use piece or weight systems — confirm by fare. See Air India baggage for the full breakdown and excess rates.
Indian passport holders are not eligible for Australia's eTA or ETA-style online entry — those are reserved for a small set of countries. Instead you must apply for the Visitor visa (subclass 600), a full tourist/visitor visa applied online via the Department of Home Affairs (often through VFS in India). Decisions can take several weeks, so apply well ahead. You'll need proof of funds, travel history, accommodation and onward plans. Always check current requirements on the official Home Affairs website before booking.
On a 12-hour non-stop, hydrate, walk the cabin and pre-select a window seat for sleep. Sydney's seasons are reversed — pack accordingly (their summer is Dec–Feb). Declare all food, plant and animal products on arrival; Australia's biosecurity fines are steep. For domestic onward travel within Australia, book separate Qantas/Virgin/Jetstar legs with a sensible buffer. Request an Asian-vegetarian (AVML) or Hindu meal (HNML) on Air India at booking.
Sydney pairs an iconic harbour with beaches, bush and a buzzing food scene. The Opera House, Harbour Bridge climb, Bondi-to-Coogee coastal walk, Taronga Zoo and day trips to the Blue Mountains are highlights. The southern summer (Dec–Feb) is beach season; spring and autumn are mild and less crowded. Sydney is also the natural gateway for onward travel to Melbourne, the Gold Coast and New Zealand.
