Another much-changed Wallabies side — already assured of a quarter-final spot — lacked fluency in the wind and driving rain but sealed a bonus-point victory that put it top above Wales.

Nic White claimed the only try of the first half and Koroibete helped himself to a brilliant individual score in the second before Jack Dempsey and Will Genia dotted down late on, while the other Australia points came from the boot of Matt Toomua.

Alexander Todua's try 10 minutes from time gave Georgia hope, but it was unable to pull off a first win over tier one opposition under Milton Haig in the coach's final game in charge.
