Exxxcellent. With the awards points difference , you can see why I would suggest not keeping crediting to QF once you have been on a candy thief challenge when an F award flight on QF from UK-Oz is less than an economy to business upgrade on QF using QF miles

(excepting if you purchase a full fare (Y fare basis) where a r/t upgrade costs 120k )
