The cheapest Delhi to Australia fares in 2026 typically route through Kuala Lumpur on AirAsia X, and November is usually the most affordable month to travel. Tuesday departures from DEL consistently price lower than weekend or Friday flights. Here is how the three main hub options stack up.
TL;DR — short answer first
For most dates in 2026, routing Delhi (DEL) to Australia via Kuala Lumpur on AirAsia X tends to be the cheapest option — often in a range that undercuts the Emirates-via-Dubai and Qantas-via-Singapore routings by around ₹10,000–₹18,000 on a round trip. November is consistently the most affordable travel month, and Tuesday departures from Delhi price noticeably lower than Friday or Sunday. That said, AirAsia X fares come with slim baggage allowances that can erode the savings once you add a checked bag. Run the numbers for your specific date on FlightGPT before committing.
The three main routing options: what you are actually choosing between
There is no nonstop Delhi to Australia flight. Every routing involves at least one stop, and the hub you connect through shapes both the price and the total travel time.
AirAsia X via Kuala Lumpur (KUL): DEL to KUL on AirAsia, then KUL to Sydney (SYD), Melbourne (MEL), or Perth (PER) on AirAsia X. Total journey to Sydney is typically around 17–19 hours including the layover, which is fairly reasonable. AirAsia X has been rebuilding its Australia network post-pandemic and the Perth route in particular is short enough that the fare holds competitive even when you factor in bag fees. The catch is that AirAsia X's bare fares include zero checked baggage — add a 20 kg bag and you are looking at a meaningful extra cost per sector. Still, the all-in number for a solo traveller with one checked bag often comes in lower than the legacy options.
Qantas or Singapore Airlines via Singapore (SIN): You might connect on Singapore Airlines itself, or on a Qantas codeshare through SIN. Singapore is geographically well-placed for Australia routes and the transit experience at Changi Airport is hard to beat if you have a longer layover. Fares here are typically in a higher range than AirAsia X — you are paying for a fuller-service product. Singapore Airlines' fares to Sydney or Melbourne can look attractive in economy, especially in off-peak months, but they rarely undercut AirAsia X all-in.
Emirates via Dubai (DXB): DEL to DXB is one of the most competitive routes in Indian aviation, with multiple daily flights from both Delhi and the rest of India. From Dubai, Emirates flies to Sydney, Melbourne, Brisbane and Perth — it operates some of the world's longest nonstop flights. The drawback for budget travellers is that Emirates economy tickets to Australia, while competitive when you factor in the generous 30 kg baggage allowance, tend to price above the AirAsia X all-in option unless Emirates has a sale. Emirates does run periodic sales worth watching — their Diwali and end-of-financial-year promotions can produce surprisingly sharp prices.
Why November is the sweet spot for Delhi–Australia
Australian summer starts in December, which pushes December and January fares sharply up. School holidays in Australia (mid-December to late January) create demand spikes from the Indian diaspora visiting family as well as leisure travellers. October–November gives you the shoulder-season price without the winter cold of July–August.
Specifically, the week around Diwali (mid-October) often sees a temporary price dip for outbound international fares from India as many travellers stay home for the festival. If your travel dates are flexible, the two to three weeks after Diwali and through mid-November are historically among the lowest-fare windows for India to Australia. Flights in this window on the DEL–SYD route can run meaningfully cheaper than peak-season equivalents.
The other underrated low-fare window: late February to late March, after Australian schools go back and before the Easter holiday surge. Fewer Indian travellers think of this window, which keeps demand — and prices — lower.
Tuesday departures: why the day of the week actually matters
It sounds like travel-blog folklore but it holds up in practice: Tuesday (and to a lesser extent Wednesday) departures from Delhi to Australia-bound connections consistently price lower than Friday, Saturday and Sunday departures. The reason is straightforward — business travellers and weekend holiday-starters fill up Thursday and Friday flights, so airlines price them higher. Tuesday is a dead zone for demand.
The difference varies by route and season. In my own searches, the gap between a Friday DEL–KUL–SYD itinerary and a Tuesday equivalent for the same travel period can be anywhere from ₹2,000 to ₹6,000 per person on a round trip. Multiplied across a family of four, that starts to matter. If you can work around your departure day, Tuesday is worth targeting on FlightGPT's flexible-date search.
One more timing tip specific to Australia: Perth is significantly cheaper to reach from India than Sydney or Melbourne because the sector from any Indian hub to Perth is shorter. If your Australia plans are flexible and Perth works for your itinerary, the fare differential can be ₹8,000–₹15,000 per person versus Sydney on the same airline. Perth to the east coast by domestic flight is cheap and frequent.
Baggage: where the AirAsia X 'cheap' option gets complicated
This is the part that catches people out. AirAsia X publishes fares that look dramatically lower than Singapore Airlines or Emirates, but those fares include zero checked baggage. For a trip to Australia — most people go for at least two weeks, many for a month or more — you almost certainly need a checked bag.
AirAsia X charges for bags on a per-sector basis. A DEL–KUL sector and a KUL–SYD sector are two separate bag charges. Adding a 20 kg bag on each sector of a return trip adds up. The total baggage add-on can sometimes narrow the gap between AirAsia X and a full-service carrier considerably. Always calculate the all-in fare including your expected bag allowance — not just the headline seat price.
Emirates and Singapore Airlines, by contrast, include 30 kg checked baggage in their standard economy fares. If you are travelling with a 25 kg bag, this is included. Qantas includes 23 kg on most economy fares to Australia. So the 'premium' carriers are not always as expensive as they look once you add the bag.
A practical table to keep in mind when comparing (always verify current terms on the airline's official booking page, as these change):
- AirAsia X: 0 kg base fare — add 20 kg per sector for a fee (check current add-on pricing at airasia.com)
- Emirates: 30 kg included on most India–Australia economy fares
- Singapore Airlines: 30 kg included on most economy fares
- Qantas: 23 kg included; check fare conditions for the specific economy sub-class
Which Australian city to fly into for the cheapest ticket?
Melbourne (MEL) and Sydney (SYD) get the most flights from India and are therefore the most competitive on price. Perth (PER) can be cheaper given the shorter routing via any hub. Brisbane (BNE) and Gold Coast (OOL) are less served from Indian hubs but worth checking if your destination is Queensland — sometimes a Melbourne or Sydney fare plus a domestic Jetstar or Virgin Australia leg is cheaper than a direct routing to Brisbane.
For travellers who want to explore multiple Australian cities, flying into one and out of another (an 'open jaw' itinerary) can actually save money compared to a return to the same city — you avoid backtracking domestically and sometimes the pair of one-way fares totals less than a round-trip. Open-jaw itineraries are searchable on FlightGPT — try DEL–SYD / MEL–DEL combinations.
Indian visa and practical notes for the Australia trip
Indian passport holders need a visa to enter Australia — there is no visa-on-arrival. The standard option is an Electronic Travel Authority (ETA, subclass 601) which is linked electronically to your passport. It costs a small government charge and is typically processed quickly, but always apply well before your travel date. Do not purchase non-refundable flights before your ETA is approved. For visa guidance, check FlightGPT's visa guide or the Australian Department of Home Affairs website directly. Student and work visa holders obviously have different requirements entirely.
On forex: Australia uses the Australian Dollar (AUD). For Indian travellers, a multi-currency forex card loaded with AUD before departure typically gives a better rate than airport exchange or using your Indian debit card at Australian ATMs. Our article on the best forex cards for Indian travellers in 2026 has more on this. Carrying some AUD cash for the first day is sensible — not everyone takes cards for small transactions.
Bottom line
AirAsia X via Kuala Lumpur is the most common cheapest routing for Delhi to Australia in 2026 — but do the all-in math including your checked bag before assuming it beats Emirates or Singapore Airlines. November and late February are your low-fare windows. Tuesday departures from Delhi consistently undercut the rest of the week. And Perth costs less to reach than Sydney if geography is flexible for you.

Frequently asked questions
What is the cheapest airline from Delhi to Australia in 2026?
AirAsia X via Kuala Lumpur is typically the lowest base fare, often undercutting Emirates and Singapore Airlines by ₹10,000–₹18,000 round trip. However, AirAsia X's bare fares include zero checked baggage — once you add a 20 kg bag for each sector, the gap narrows. Always compare all-in fares for your specific bag allowance need at airasia.com and on FlightGPT.
Is it cheaper to fly Delhi to Sydney or Delhi to Melbourne?
Sydney and Melbourne are usually priced similarly as both are heavily served from India. Perth (PER) is often ₹5,000–₹12,000 cheaper per person on a round trip because the routing from any Indian hub to Perth is shorter. If your plans are flexible, Perth + a cheap domestic Jetstar or Virgin Australia leg to the east coast can save money overall.
What month is cheapest to fly from Delhi to Australia?
November is historically the most affordable month — post-Diwali demand dips, Australian spring shoulder season, no school holidays. Late February to late March is the second-best window. Avoid mid-December to late January (Australian summer school holidays) when fares spike significantly.
How long is the flight from Delhi to Sydney with a stopover?
Total journey time varies by hub and layover duration. Via Kuala Lumpur, expect around 16–20 hours including the connection. Via Singapore, 17–20 hours. Via Dubai, 18–22 hours given the longer Dubai–Sydney sector, though Emirates' A380 flights are comfortable for the distance. A shorter layover (2–3 hours) reduces total time but leaves less buffer for connection issues.
Does Emirates or AirAsia X include baggage from Delhi to Australia?
Emirates includes 30 kg checked baggage on most standard economy fares. AirAsia X's base fares include zero checked baggage — each sector (DEL–KUL and KUL–SYD for example) requires a separate baggage add-on at current AirAsia rates. Always verify on the airline's booking page before purchasing, as these policies change. For a traveller with a 25 kg bag, Emirates can sometimes work out cheaper than AirAsia X all-in.
Do Indians need a visa for Australia?
Yes. Indian passport holders need a visa — the most common is the Electronic Travel Authority (ETA, subclass 601), which is electronically linked to your passport and processed online through the Australian Department of Home Affairs or authorised apps. Apply before booking non-refundable flights. Processing is usually fast but not instant — allow at least a few days. See the FlightGPT visa guide at /visas for a summary.
