What is the flight path from London Heathrow to Sydney Australia?

THE FLIGHT PATH LHR TO SYD IS CALLED EASTERN HEMISPHERE (EH) ROUTE BUT IF ITS LHR- ANY JAPNESE OR KOREAN CITY -SYD IT IS CALLED TRANS SIBERIAN (TS) ROUTE. SINCE THE WORLD IS ROUND WE CAN FLY EVEN CROSSING BOTH ATLANTIC AND PACIFIC OCEANS AND THE ROUTE WILL BE CALLED ATLANTIC PACIFIC (AT) ROUTE IT IS BETTER NOT TO TRAVEL VIA AP ROUTE.
