Justin Tipuric and Sam Warburton are two contenders for a back-row spot against the Wallabies
Graham Rowntree has paid a glowing tribute to British & Irish Lions captain Sam Warburton.
The Wales flanker reportedly faces a battle to earn Test selection with fellow countryman Justin Tipuric in red-hot form.
But Rowntree, who is also England's forwards coach, has sung the praises of Warburton ahead of tomorrow's clash with NSW Waratahs.
"I have been very impressed with Sam," said Rowntree.
"He is very professional. He is certainly not showing any signs of stress or pressure.
"Like all the other players, he goes about his business. I have been really impressed with him as a person.
"He is a doer, and a lot of guys are following his lead in terms of his attitude to training, his diligence.
"It is not getting any easier in terms of selection. There are a lot of guys putting their hands up.
"We will get tomorrow out of the way, and then Tuesday (against the Brumbies), and then we will pick a Test team. That is the truth."
The Lions lineout miss-fired at times during last Tuesday's 64-0 victory over a Combined Country XV in Newcastle, and the Waratahs have been boosted by the inclusion of Dave Dennis, who has faced Warburton and Wales four times.
"Dave Dennis coming back in will bolster their lineout for tomorrow. He's a good player, he has got some Test experience," added Rowntree.
"We had a few issues in the lineout on Tuesday night. We dropped three from 16, but a lot of that was just personnel that hadn't played a lot together.
"That's what you get on a tour like this. You take it on the chin and move on.
"I actually thought they battled very well as a pack on Tuesday night. They didn't really get enough credit for the performance they put in."
As the countdown continues for RWC2015, Tournament Chief Executive Debbie Jevans visited the Millennium Stadium to discuss preparations for the eight matches and reveal the positive news that 100,000 tickets for games at the home of Welsh rugby have sold in the last seven days.
Jason Harries is targeting a first win on the World Series circuit this season with Wales. The series returns to action this weekend in Dubai where Harries is part of a team hoping to build from its efforts in round one in October.
Wales skipper Jevon Groves says his side have addressed a few points from Gold Coast and aim to 'hit the ground running' in the next two rounds of the World Series, kicking off with this weekend in Dubai before heading off to South Africa next week.
Wales Sevens manager Steff Thomas is hopeful his side can build from a quarter-final spot in the opening round of the World Series in Australia when his side take part in the forthcoming double header in Dubai and South Africa.
