Let’s be real. Flying across the Nullarbor is a bit of an endurance test. It is one of the longest domestic routes in the world, and honestly, the pricing for perth to melbourne flights can feel like a total gamble. One day you’re looking at a cheeky $155 one-way on Jetstar, and the next, Qantas wants $600 for a seat that doesn't even have extra legroom.
If you've ever sat in Perth Airport (T3/T4 for the Qantas and Jetstar folks, T1/T2 for Virgin) wondering why the person next to you paid half what you did, you aren't alone. Most people treat booking these flights like a game of roulette. But after years of watching the trends, especially as we head into 2026, there is a method to the madness. It is about timing, sure, but it's also about understanding the weird physics of Australian air travel.
The Brutal Reality of the Red-Eye
You’ve seen them. The flights that depart Perth at 11:45 PM and dump you into Melbourne Tullamarine at 6:15 AM.
They are cheap. They are also exhausting.
The time difference is the real killer here. Melbourne is three hours ahead of Perth (during Daylight Savings). When you take a 3.5-hour flight east, you essentially lose an entire night. You land in Melbourne feeling like a zombie while the rest of the city is just grabbing their first flat white. If you’re a "sleep anywhere" person, these midnight runs are the gold standard for saving cash. If you aren't, the $50 you saved will be spent immediately on caffeine and a hotel room you can't check into yet.
Which Airline Actually Wins the Perth to Melbourne Route?
We have the big three: Qantas, Virgin Australia, and Jetstar.
Jetstar is the obvious choice for the budget-conscious, often hovering around that $130 to $180 mark if you book at least four weeks out. But watch the baggage. They will weigh your carry-on with the intensity of a diamond appraiser.

Virgin Australia is usually the middle ground. Their 737s and the newer MAX 8s are frequent flyers on this route. You'll often find they price-match Jetstar’s "plus baggage" tiers, making them a more comfortable choice for just a few extra bucks.
Then there’s Qantas. They run the A330 wide-body jets on specific morning and afternoon frequencies. Honestly, if you can snag an A330 for your perth to melbourne flights, do it. The 2-4-2 seat configuration feels way less claustrophobic than the standard narrow-body planes. Plus, you get a hot meal that isn't just a tiny packet of pretzels.
- Jetstar: Cheapest, no-frills, strict on weight.
- Virgin: Reliability and decent points earn.
- Qantas: The "lux" choice, better planes (A330s), more expensive.
Why Thursday is Your Secret Weapon
Most people book for a Friday afternoon departure. Huge mistake.
Data from 2025 and early 2026 consistently shows that Thursday is the "sweet spot" for departures. Business travelers are usually heading home on Thursdays, and the weekend crowd hasn't arrived yet. If you can shift your trip by 24 hours, you’re looking at an average saving of about 15-20%.
Tuesday is another weirdly cheap day, but only if you aren't flying during school holidays. Avoid Mondays at all costs. Between corporate flyers and the "FIFO" (Fly-In Fly-Out) crowd returning to the east, Monday morning flights are almost always overpriced.
The Myth of the Last-Minute Deal
Forget what you heard in the 90s. There is no such thing as a "last-minute deal" at the airport counter.

If you try to book perth to melbourne flights less than seven days before departure, you are going to get fleeced. In 2026, the algorithms are smarter than ever. They know that if you’re booking 48 hours out, you need to be on that plane, and they will charge you $800 for the privilege.
The "Golden Window" is 4 to 6 weeks. Any earlier and you might miss a flash sale. Any later and the price floor starts rising.
Beyond Tullamarine: Is Avalon Worth It?
Sometimes you’ll see a flight that looks impossibly cheap. Look closer. It’s probably flying into Avalon (AVV) instead of Tullamarine (MEL).
Avalon is great if you’re headed to Geelong or the Great Ocean Road. If you’re trying to get to the Melbourne CBD, though? It’s a trek. You’ll spend an hour on the SkyBus or a small fortune on an Uber. Always factor that ground transport cost into the "cheap" ticket price.
Most direct flights from Perth still land at Tullamarine, which is roughly 20-30 minutes from the city center depending on that lovely Melbourne traffic.
Dealing With the "Empty Flight" Logic
Airlines hate flying empty seats. If a flight is looking sparse 21 days out, they’ll trigger a "tactical sale." This is why price alerts are actually useful. Set one up on Google Flights or Skyscanner for your specific dates. Don't just check once and give up.

Also, consider the "split ticket" strategy. You don't have to fly the same airline both ways. Sometimes Jetstar is cheapest on the way over, but Virgin has a better return fare. It takes five extra minutes to check, and it can save you $100.
Navigating the Seasons
Perth and Melbourne have totally different vibes. When Perth is hitting 40°C in February, everyone wants to escape to Melbourne’s (slightly) cooler cafes.
- Cheapest months: May and June. It’s cold in Melbourne, but the flights are a steal.
- Most expensive: December and January. School holidays + Christmas = pain for your wallet.
- The "Shoulder" sweet spot: October. The weather is turning nice in both cities, and the prices haven't spiked for the holidays yet.
Making the Most of the 3,000km Trek
It’s a long way. 2,700 kilometers of desert, basically.
If you’re flying Virgin or Qantas, check the WiFi status. Not every plane has it yet, and there is a massive dead zone over the center of the country where even the best satellite connection struggles. Download your podcasts before you leave Perth.
And for the love of everything, stay hydrated. The air on these cross-continental flights is drier than the Nullarbor itself.
Actionable Steps for Your Next Booking
Stop guessing and start booking smarter. To get the best deal on perth to melbourne flights, follow this checklist:
- Set a Price Alert: Do this at least 8 weeks before you plan to fly.
- Aim for Thursday: If your schedule allows, avoid the Friday/Sunday peak.
- Check the Plane Type: On the Qantas site, look for the "A330" icon for a much better seat experience.
- Watch the Terminal: Remember that Jetstar and Qantas are in a separate building from Virgin at Perth Airport. Don't get dropped off at the wrong one; it’s a long walk.
- Calculate the "Real" Cost: Add your bags and seat selection before you compare prices between a budget carrier and a full-service airline.
The flight is just the beginning. Once you hit the ground in Melbourne, grab a Myki card at the airport, jump on the SkyBus, and go find yourself a decent coffee—you’ve earned it after that trek.
