There's also the commercial reasons for the stop - they can serve SIN, HKG etc on the same flight with only an hour or two layover. Therefore a flight LHR-SYD could sell seats for LHR-SIN, SIN-SYD and LHR-SYD.
Plus 24-26 hours on a plane is long enough with a stop, I don't think many passengers would go for it over having that short layover in Asia.

Quoting WROORD (Thread starter): According to Boeing website the 777-200LR can reach Australia with full loads:
The devil is in the details -
What is a "full load"? In the case of the Boeing chart it is not an airplane full of passengers and cargo. It is an airplane full of passengers with minimum cargo.
Second, where is the chart centered on Sydney? Just because boeing says LON-SYD is doable, it does not mean SYD-LON can be done. SYD-LON is slightly more challenging because of prevailing winds along the quickest path.
Finally... There is the profitability question. It has to make money and ULH flights are very expensive.
