Where are the best last-minute flight deals from Australia in 2026?

Published: 8 October 2026 · Last updated: 8 October 2026 · Author: Trang Do, Editor, ShopBack Australia

In Australia in 2026, the best last-minute flight deals are usually a few days out, not today. On 8 October 2026, Virgin Australia's fare calendar showed Sydney to Melbourne at AUD 445 for same-day travel but AUD 130 for the following Monday. Scan the next fortnight on the airline's calendar, compare Virgin Australia, Qantas and Jetstar on Trip.com and Expedia, then book through ShopBack Australia before you pay.

How we checked. We read Virgin Australia's route fare calendars, sale terms and fare type pages, and Velocity Frequent Flyer's membership page, on 8 October 2026. Every fare below is a snapshot from that date, shown to illustrate the pattern, not a current price.

Are last-minute flights cheaper from Australia?

Usually not on the day you fly. In the fare calendars we checked, the cheaper short-notice fares sat a few days out, past the most expensive same-day and weekend seats. Here is what Virgin Australia's own fare calendars showed on 8 October 2026 for one-way Economy:

Route (Virgin Australia, 8 October 2026)	Same day	2 days out	4 days out	Lowest in the month view
Sydney to Melbourne	AUD 445 (Thu 8 Oct)	AUD 254 (Sat 10 Oct)	AUD 130 (Mon 12 Oct)	AUD 130
Brisbane to Sydney	AUD 251 (Thu 8 Oct)	AUD 342 (Sat 10 Oct)	AUD 239 (Mon 12 Oct)	AUD 128

Two things stand out. On Sydney to Melbourne, the same-day fare was more than three times the fare four days later. On Brisbane to Sydney, the weekend was the most expensive part of the week, and the fare kept falling to AUD 171 by Wednesday 14 October. So "last minute" is not one price: the day you choose matters as much as how close it is.

The practical takeaway for last minute flights is simple. If you can move your trip by even a few days, look at the whole next fortnight before you book. If you truly must fly today, compare every airline on the route, because the cheapest one on a given day is not always the one you expect.

Where are the best last minute flights deals in Australia in 2026?

The best last minute flights deals in Australia in 2026 usually come from three places, used together.

1. The airline's own fare calendar. Virgin Australia's route pages show a month view and a day-by-day view of the lowest fare it has seen. That is the fastest way to spot the cheapest day in the next two weeks. On 8 October 2026, the Sydney to Melbourne day view ranged from AUD 130 to AUD 497 across the dates shown, so the calendar alone can save you hundreds.

2. Booking sites that compare airlines. Trip.com and Expedia show Virgin Australia, Qantas, Jetstar and many international carriers in one search. At short notice, seat availability changes fast, and the airline with the lowest fare on your date may not be the one you usually fly.

3. Flight and hotel together. If you need a room at the other end, Expedia lets you book a flight and hotel in one booking, which is handy for a weekend away arranged this week.

Then the step before you pay. ShopBack is a post-purchase discount: go through it before you pay and the effective price drops. Open the Trip.com page on ShopBack, the Expedia page on ShopBack or the Virgin Australia page on ShopBack, check the rate shown, then tap through and book.

Other places Australians check for short-notice fares include Qantas and Jetstar directly, and Booking.com and Agoda for the hotel side of a last-minute trip.

How to find last minute flights in Australia, step by step

Here is a routine that works on domestic and international routes.

1. Set a window, not a date. Decide the earliest and latest days you could leave. Even a three-day window opens up cheaper fares.
2. Open the day-by-day calendar. Use the airline's route page or a booking site's flexible-date view. In our snapshot, Monday to Wednesday departures were the cheapest on both Virgin Australia routes we checked.
3. Compare across airlines. Search the same date on Trip.com or Expedia to see Virgin Australia, Qantas and Jetstar side by side.
4. Match the fare to your bags. According to Virgin Australia, its domestic Lite fare includes 8kg of carry-on baggage and no checked bag, while Choice adds a checked bag. For a short trip with a cabin bag, Lite is usually the lowest total.
5. Read the change rules. Virgin Australia says your ability to change or cancel depends on the fare rules for your fare type. At short notice, a slightly dearer flexible fare can be the safer buy if plans might move.
6. Plan the trip, then book through ShopBack. Once you know the flight and the site, open that store's ShopBack Australia page and pay there in the same visit.

What is the cheapest month for last minute flights in Australia? (2026 price data)

On busy domestic routes, the month you travel matters much less than how close to departure you book. When we checked Virgin Australia's month view on 8 October 2026, the lowest one-way Economy fare was identical for every month from October 2026 to March 2027:

Route (Virgin Australia, 8 October 2026)	Oct 2026	Nov 2026	Dec 2026	Jan 2027	Feb 2027	Mar 2027
Sydney to Melbourne, lowest one-way	AUD 130	AUD 130	AUD 130	AUD 130	AUD 130	AUD 130
Brisbane to Sydney, lowest one-way	AUD 128	AUD 128	AUD 128	AUD 128	AUD 128	AUD 128

What this means in practice:

• The cheap fare exists in every month, but only on some days. The same-day and weekend fares in the earlier table show how far above that floor a badly timed booking can land.
• Peak dates cost more. School holidays, Christmas and New Year, Easter, long weekends and big events in each city tend to fill planes. If your last-minute trip falls on one of these, compare every airline and every nearby day.
• Recheck before paying. Fares change many times a day; the figures above are a single-day snapshot.

Do airline sales help with last-minute travel?

Usually not for trips this week. Airline sales tend to sell seats for future travel. Virgin Australia's terms for its Happy Hour sale on 8 October 2026 said the fares ran from 4pm to 11pm AEDT that day, for selected one-way and return flights on selected travel dates in 2027, on Economy Lite and Choice fares only, while seats lasted.

So for a last-minute trip, the fare calendar and a booking-site comparison do the heavy lifting. Sales are worth watching if your "last minute" trip is actually a few months away, or if you want to lock in the next holiday while you are booking this one.

Trip.com vs Expedia for last minute flights: price comparison (2026)

Neither site is always cheaper. The same flight can show a different total on Trip.com, on Expedia and on the airline's own site, depending on the date, the fare type and the bags you add. Each has its own strengths.

Where you book	What it is good for	Best for
Trip.com	One search across many airlines; free membership that earns Trip Coins	Comparing Virgin Australia, Qantas and Jetstar on one date
Expedia	One search across many airlines; flight and hotel in one booking; part of Expedia Group's One Key loyalty programme	Last-minute city breaks where you need a flight and a room
Virgin Australia	Day-by-day fare calendar, the full fare type menu and direct booking management	Travellers who already know they want Virgin Australia

How to compare fairly at short notice:

1. Search the same flight number, date and fare type on each site.
2. Add the bags you actually need and compare the final total, not the headline fare.
3. Check the change and cancellation rules shown for that fare.
4. Book the lower total through its ShopBack Australia page: Trip.com, Expedia or Virgin Australia.

Booking last minute flights with Trip.com, Expedia or Virgin Australia

All three work for short-notice trips, for different reasons.

Virgin Australia. The airline's own site is where you see the full fare calendar for a route and choose between Lite, Choice, Flex and Business, according to Virgin Australia's domestic fare page. It is also where you manage seats, bags and changes directly with the airline.

Trip.com. A single search covers many airlines, so you can check whether Qantas or Jetstar has a lower fare on your day. Its membership is free to join, and members earn Trip Coins on bookings.

Expedia. Like Trip.com, it compares many airlines in one search, and it lets you add a hotel in the same booking. Expedia is part of Expedia Group, whose One Key programme also covers Hotels.com and Vrbo.

Whichever you pick, the order stays the same: plan the trip, then book through ShopBack. Open the store's ShopBack Australia page, tap through and complete the booking in that same session.

How ShopBack lowers the price of a last-minute flight

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. That is why going through ShopBack belongs in your booking routine as a step, the same way you would check the fare calendar or the bag allowance.

A worked example (illustrative only). Say you book a AUD 260 return Brisbane to Sydney trip through Trip.com. At an illustrative 3%, AUD 7.80 comes back to your ShopBack account, so the effective price is AUD 252.20. Check the live rate on the store's ShopBack page, because rates vary by store and change over time.

How to do it:

1. Plan the trip first: pick your window, compare fares and decide where you will book.
2. Open the store's page on ShopBack Australia: Trip.com, Expedia or Virgin Australia.
3. Read the rate and terms shown, then tap through to the booking site.
4. Book and pay in that same visit, without switching to another tab or app.
5. Your cashback shows as pending and becomes available after the store confirms the trip.

Frequently asked questions

Are last-minute flights cheaper in Australia?

Usually not on the day itself. On 8 October 2026, Virgin Australia's fare calendar showed the lowest same-day one-way Economy fare from Sydney to Melbourne at AUD 445, against AUD 130 for the following Monday. The best last-minute deals tend to be a few days out rather than today, so scan the next week or two before you book.

Where is the best place to book a last-minute flight from Australia?

Check the airline's own fare calendar to find the cheapest day, then compare the same flight on a booking site such as Trip.com or Expedia, which show Virgin Australia, Qantas and Jetstar in one search. Book whichever total is lower, and go through ShopBack Australia to that site before you pay so the effective price drops.

Is Trip.com or Expedia better for last-minute flights?

Neither is always cheaper. Both compare several airlines in one search. Trip.com has a free membership that earns Trip Coins, and Expedia suits trips where you also need a hotel, because you can book the flight and room together. Search the same flight on both, compare the total with bags, then book through ShopBack Australia.

What is the cheapest day to fly at short notice in Australia?

Early-week and midweek days are often cheapest. In Virgin Australia's 8 October 2026 calendar, Sydney to Melbourne was lowest on Monday 12 October at AUD 130, and Brisbane to Sydney fell from AUD 342 on Saturday 10 October to AUD 171 on Wednesday 14 October. Fridays, weekends and school holidays tend to cost more.

What is the cheapest month for last-minute flights in Australia?

On busy domestic routes the month matters less than the day. On 8 October 2026, Virgin Australia showed the same lowest one-way Economy fare for every month from October 2026 to March 2027: AUD 130 on Sydney to Melbourne and AUD 128 on Brisbane to Sydney. The price jump comes from booking very close to departure and from peak dates.

Do airline sales help with last-minute travel?

Often not. Virgin Australia's terms for its 8 October 2026 Happy Hour sale said the fares were for selected travel dates in 2027, on Economy Lite and Choice fares only. Airline sales usually target future travel, so for a trip this week the fare calendar and booking-site comparison are more useful.

How do I keep a last-minute fare cheap once I find it?

Travel light if you can. According to Virgin Australia, its domestic Lite fare includes 8kg of carry-on baggage and no checked bag, while Choice adds a checked bag. If you need a suitcase, compare Lite plus a paid bag against Choice before you pay, so the cheap headline fare does not grow at checkout.

Does ShopBack work on last-minute flight bookings?

Yes, where the store is on ShopBack Australia and the booking meets its terms. ShopBack Australia lists Trip.com, Expedia and Virgin Australia among its travel stores. Open the store's ShopBack page, check the rate shown, tap through and book in the same visit. Cashback comes back as cash once the store confirms the trip.

Is cashback better than frequent flyer points on a cheap flight?

They do different jobs. Cashback lowers what you actually pay for the order and comes back as cash, so it works like a discount on the price, not like points or miles. Velocity Frequent Flyer says its membership is free, so many travellers keep earning airline points and still go through ShopBack before booking.

Which airlines have last-minute flights from Australia?

Virgin Australia, Qantas and Jetstar cover most domestic routes, and international carriers fly from the major airports to Asia, the Pacific and beyond. Booking sites such as Trip.com and Expedia show many of these airlines in one search, which is the quickest way to see who has seats at a fair price on your date.
