It isn’t just Qatar Airways which has excellent business class deals to Australia at the moment.
Air India has launched a great fare from Heathrow to Melbourne or Sydney – just £1,825 return. The fare is available throughout much of 2018. You will be getting a new Boeing 787 with flat bed seats.
Air India is a member of Star Alliance so you can credit the miles to Lufthansa Miles & More, United MileagePlus, SAS EuroBonus or one of the other main Star Alliance schemes. You don’t need to credit them to Air India.
Your best option to maximise your miles when paying is American Express Preferred Rewards Gold. This offers double points – 2 per £1 – when you when you book flight tickets directly with an airline. Our review of Amex Gold is here.
If you want to pay even less you can – until TOMORROW ONLY – book a fantastic deal in the Qatar Airways sale. Oslo to Melbourne / Sydney / Perth / Canberra / Auckland is around £1475 return. The Norway Qatar Airways sale page is here and my full article on the Qatar Airways sale is here which discusses the best aircraft types to pick.
It is also worth pricing tickets out of Stockholm (Sweden Qatar Airways sale page here). You may pay a little more but Stockholm is more convenient if you are starting in the regions.
Remember that Europe to Australasia is 600 British Airways tier points (560 to Perth) when you fly on Qatar Airways.
