In fact, you can. BA F to LHR and then QF LHR-SYD on the A380 in F

That flight stops for fuel in SIN but counts as a single segment as it is a single flight number.
That is an exceptional flight, looks like the stars are aligning for you mate. My parents have done Qantas and Singapore in A380 F and I've done Emirates and Singapore. They are all great and all have Dom so no worries
The Qantas Lounge in Sydney is one of the best in the world, another great aspect of the QF F flight.
How long are you planning on taking to do all this? I'd love to be able to take 6 months or so and really go slow. Like I said, shoot me a message if you want to know more about any of the cities, I'll fill you in
