The Wallabies were decimated by injury against Ireland in the penultimate match of their tour,with Taniela Tupou (ankle),Rob Valetini (ankle),Andrew Kellaway (foot),Hunter Paisami (knee),Nic White (concussion),Dave Porecki (concussion) and now Hooper are all set to miss a must-win Test against Wales.
Australia have an even greater selection headache this week given overseas-based stars No.10 Bernard Foley and second-rower Will Skelton are unavailable because the match falls outside the international window.
