Wales assistant coach Shaun Edwards believes his side finally boast the strength in depth to end their decade-long hoodoo against the Wallabies.

The teams meet on Saturday (Sunday 0420 AEDT) at the Principality Stadium in Cardiff – a venue the Wallabies haven’t tasted defeat at since 2008.

Michael Cheika’s side have won the last 13 encounters but head in to the game struggling for form and confidence having tasted victory in just three of their last 12 matches.

The Welsh have been similarly bullish about their chances for the last two years only for the tourists to win comfortably and Edwards pinpointed the lack of options from the bench as the biggest difference between the two sides.

The hosts have won their last six matches, including a series victory in Argentina in addition to a 22-20 success over South Africa in Washington DC in June.

Last Saturday Warren Gatland’s side were sluggish in their 21-10 win over Scotland, but Edwards said the fact several key players sat out the game showed the squad is stronger than in previous years.

British and Irish Lions duo Liam Williams and Dan Biggar missed the game but are expected to return on the wing and at five-eighth respectively and star loosehead prop Rob Evans is also set to start following injury.

“Every time it (Australia) comes around, you are hoping to break that (losing run),” Edwards said.

“In the past, they have definitely got us off the bench.

“Their bench has been very strong, and games have been won and lost in the last five-10 minutes.

“I think we are stronger now, and there is no doubt, when you look at a rugby team, sometimes you see how strong it is when you look how good the bench is.

“I think our bench is looking definitely better than it has been in the past.”

The match will be the last meeting between the sides before they do battle in their World Cup pool match in Japan.

Edwards insists Saturday’s match or previous matches have little to no relevance about what will happen in Tokyo next September.

“A couple of years ago, we went to Scotland and had beaten them 10 times on the bounce. We went up to Scotland, and they did a job on us,” he said.

“I don’t honestly believe that one game has anything to do with the next.

“But there is no doubt for the public of Wales and the rugby fans, it would definitely give them a boost that they (Wales) actually can beat them.”
