How to Find Cheap Flights in Australia 2026: 15 Proven Tips to Save Hundreds

Tip 1: Book domestic flights 3–6 weeks out. Counterintuitively, booking too far in advance often means paying premium "early bird" fares. For domestic routes (Sydney–Melbourne, Brisbane–Perth, etc.), the sweet spot is typically 3–6 weeks before departure. Airlines release cheaper seat blocks closer to departure to fill remaining inventory.

Tip 2: Book international flights 2–6 months out. International pricing is more complex. Popular routes to Bali, Japan, London, and the USA tend to hit their lowest prices 2–6 months before departure. Booking too early (9–12 months out) often means full fare prices before promotional inventory is loaded.

Tip 3: Fly mid-week when possible. Tuesday and Wednesday departures are consistently cheaper than Friday and Sunday flights. If your schedule has any flexibility, this single adjustment can save $50–$200 per person on popular routes.

Tip 4: Use Google Flights' calendar view. Google Flights has a "lowest fares" calendar view that shows price variations across an entire month at a glance. Shifting your departure by even one or two days can unlock significant savings. Set up price tracking alerts for routes you're planning.

Tip 5: Try the Hopper app for price prediction. Hopper uses machine learning to predict whether a fare will go up or down, and advises you to book now or wait. It's not perfect, but it removes the guesswork for travellers anxious about missing a deal.

Tip 6: Compare on Skyscanner, Google Flights, and Kayak AU. No single comparison site surfaces every fare. Skyscanner is particularly good at finding low-cost carrier options, Google Flights excels at flexible date search, and Kayak AU sometimes surfaces deals the others miss. Check all three for high-value bookings.

Tip 7: Search nearby airports. Flying into Avalon instead of Melbourne Tullamarine, or Gold Coast instead of Brisbane, can mean dramatically cheaper fares - especially on Jetstar. Factor in ground transport costs, but the net saving is often still substantial.

Tip 8: Jetstar for leisure routes. Jetstar covers most major Australian leisure routes and is consistently the cheapest option when you fly carry-on only and avoid optional extras. Their fare sales (watch for 24-hour flash sales) can be genuinely extraordinary.

Tip 9: Rex Airlines for regional routes. Regional Express (Rex) flies routes that Qantas and Virgin have abandoned, including many regional NSW, Victoria, and SA destinations. On competitive routes, their fares are often lower than the legacy carriers.

Tip 10: Watch for positioning flights. Positioning or "deadhead" flights - where an aircraft needs to reposition to another city - are sometimes released at very low prices. These are rare but worth monitoring on deal aggregators.

Tip 11: Monitor error fares. Airlines occasionally publish fares at a fraction of their intended price due to system errors or currency conversion mistakes. Sites like Secret Flying and Airfarewatchdog aggregate these globally. Act fast - they're usually corrected within hours. Most airlines honour confirmed bookings, but read the fine print.

Tip 12: Test VPN pricing cautiously. Some airlines show different prices based on the country you're browsing from. Using a VPN to check fares from lower-cost markets can occasionally surface cheaper prices - but pay in your local currency to avoid foreign exchange fees that eat the saving. This is increasingly difficult as airlines detect and block it.

Tip 13: Consider points redemptions for premium travel. Frequent flyer points (Qantas Points, Velocity Points) are most valuable when redeemed for business class international travel, where cash prices are $4,000–$10,000+. For economy domestic flights, the maths often favours cash. Evaluate each redemption individually rather than using points out of habit.

Tip 14: Fly hand luggage only. Checked baggage fees add $30–$80 per leg on budget carriers. A carry-on-only discipline - especially for short trips - significantly reduces the total cost. Invest in a quality 20L backpack that fits under the seat and skips even the overhead bin queue.

Tip 15: Compare airport parking versus ride share. For long trips, airport parking costs can exceed $100 for a week. Platforms like Parkopedia or Wilson Parking's online rates versus Uber/DiDi from home can swing either way depending on distance. Calculate the full door-to-gate cost for each option.

Finding cheap flights isn't about a single hack - it's about stacking small advantages. The traveller who books mid-week, uses Google Flights' calendar view, flies carry-on only, and monitors Jetstar sales will pay dramatically less than someone who books a Friday flight six months out on Qantas' website.
