Wales lock Luke Charteris has praised his Australian opponent Nathan Sharpe ahead of this weekend's clash in Cardiff on Saturday.
Sharpe is set to play his final match before retirement against Wales, bringing to a close an outstanding career for Australia and one for which Charteris has the upmost respect.
"Is it his last game this time? He has retired a few times and keeps coming back!" said Charteris.
"Seriously, I've been lucky enough to go up against him a few times, and he is a quality player.
"He really is one of the standout second-rows of the last 10 or 15 years, and if this is his last game then he has certainly earned his rest."
Wales have fallen narrowly to Australia in five encounters over the the last 13 months, with Charteris desperate to turn the tide.
"The games have been pretty close, yet it's 5-0 to Australia and that does not look good," added Charteris.
"We know that we are capable of beating them, it is just making sure we nail the little moments that have cost us in the past.
"We know their individual players better than other teams, but it's not a case of knowing what to expect. We still have to do our homework and see what new challenges they have brought into their game.
"It is the last game of a long season for them and their bodies will be tired, but at the back of their minds they know that they are 80 minutes away from being on the beach with their feet up."
