How would they route SYD to LHR?
Take off and set heading 319 degrees and just keep going?
The Great circle route takes you across the South China Sea - right through the middle of China, up the top of Kazakhstan and down, across Western Russia then down through Estonia and the Baltic to Britain...
Stretch that string down to the south a little and it only adds a few hundred km to the trip.
