What airports serve London Heathrow to Sydney flights?

What are the stopover options between London Heathrow to Sydney?

It’s generally a much cheaper flight but takes extra time - sometimes up to 54h. The stopovers on single connection flights can be lengthy too. For example, flights with British Airways via Hong Kong can have stopovers with durations of 10-19h, so make sure you check these when booking.
