Australia coach Michael Cheika added four youngsters to his squad to travel to Europe for the Spring Tour.
Queensland Reds pair Izaia Perese and Taniela Tupou and Waratahs duo Jack Dempsey and Andrew Kellaway will join the squad.

Perese is the youngest of the quartet at 19 years of age.
The Wallabies begin the tour against Wales on November 5, before meetings with Scotland, France, Ireland and England.
