A return business class flight from Sydney to London retails for somewhere between $8,000 and $15,000, depending on the airline and how far in advance you book. Last year, I flew it in Qantas Business — lie-flat seat, proper meals, pyjamas — and paid $415 in taxes and fees. Here's exactly how I did it, without using any complicated credit card churning strategies or spending money I wouldn't have spent anyway.

The Foundation: Understanding How Australian Points Programmes Work

There are two main frequent flyer programmes relevant to Australian travellers: Qantas Frequent Flyer and Virgin Australia Velocity. Both allow you to earn points through flying, credit card spend, and a range of retail and service partners. Both allow you to redeem those points for flights — either through their own metal (Qantas or Virgin aircraft) or through partner airlines. The key to earning a business class redemption without paying for it is accumulating points efficiently without needing to fly excessively to do so.

Step One: The Right Credit Card

The most efficient way to accumulate points as an Australian who isn't a road warrior is through credit card spend. I hold an American Express card that earns Membership Rewards points, which transfer to Qantas Frequent Flyer at a ratio that made sense for my redemption target. The card has an annual fee, which is significant, but offset by travel credits, lounge access, and — most importantly — the points I earn on everyday spending.

Every dollar I spend on the card earns points. Groceries, fuel, utilities where the provider accepts American Express, online subscriptions, work expenses that I pay personally and claim back — all of it accumulates. I also put as much discretionary spend as possible on the card: renovations, large purchases, anything where credit card fees aren't charged.

Step Two: Sign-Up Bonuses

The single biggest accelerant to my points balance was the sign-up bonus offered when I first applied for the card. These bonuses — typically requiring a minimum spend in the first few months — can deliver enough points for a one-way business class flight on their own in some cases. I met the minimum spend organically by timing my application before a period of predictably higher expenditure (a home renovation).

I'll note here that credit card sign-up bonuses can tempt people into spending more than they otherwise would, which defeats the purpose entirely. The only way this works financially is if you spend the same amount you would on a debit card, just via credit card instead, and pay the balance in full every month. Interest charges will wipe out any points value many times over.

Step Three: Partner Points

Beyond credit card spend, I supplemented my balance through Qantas partner programmes. Qantas Frequent Flyer has partnerships with a significant number of everyday businesses — health funds, energy providers, car hire companies, hotels, and grocery programmes. Switching some of my existing spending to Qantas-linked providers added a meaningful number of points per year without any additional expenditure.

I also transferred Woolworths Everyday Rewards points to Qantas periodically, which added another modest but consistent stream to my balance.

Step Four: The Redemption Strategy

Having accumulated enough points for a business class award, the next challenge is actually booking it. Classic reward seats — the fixed-point-cost seats that represent genuine value — are limited on popular routes. Sydney to London via Qantas requires booking well in advance (I started looking six months out) or being flexible about dates.

I found a one-way Sydney to Singapore to London classic reward in Qantas Business. The points cost was significant — I used the majority of my balance — but the redemption value, calculated against the retail price of the same seat, was excellent. I combined this with a cheaper economy return from London to Sydney on a separate booking to make the overall trip work financially.

The Actual Cost

Points: the accumulated balance from approximately 18 months of credit card spend, sign-up bonuses, and partner earnings. Cash: $415 in taxes and carrier charges, plus the annual fee on my credit card ($450 per year, offset in part by travel credits). The business class seat would have cost approximately $8,500 at the sale price I saw on the Qantas website for the same dates. The maths is compelling.

Is This Strategy Worth It for Every Australian?

Not necessarily. It requires discipline with credit card spending, patience to accumulate points over time rather than expecting instant results, and some comfort navigating points programme rules and redemption availability. It works best for people who already spend a meaningful amount on everyday expenses and can consolidate that spend onto a rewards card without changing their habits. If you carry a credit card balance, this strategy is not for you.

But for the Australian traveller who pays their balance monthly, spends at least $2,000-$3,000 per month on debit currently, and has a dream flight in mind — building toward a business class redemption is genuinely achievable within one to two years. The experience of flying flat-bed to London rather than 24 hours economy is transformative enough that, once you've done it, going back is genuinely difficult.

Is This Strategy Still Available in 2026?

Yes — the credit card welcome bonus arbitrage that funds business class flights is alive and well in Australia in 2026. The Qantas American Express Ultimate and Premier Platinum cards continue offering 100,000–200,000 point welcome bonuses for new applicants meeting minimum spend requirements. The key constraint is the "once per lifetime" rule on most cards — you can only earn a particular card's welcome bonus once. The strategy works best for Australians who haven't previously held premium travel credit cards, and who have a period of high natural spending (renovation, new car, business investment) against which to meet the minimum spend without artificial expenditure.
