Dempsey was sidelined for nearly 12 months when he sustained nerve damage after his hamstring was ripped from the bone in a match against the Barbarians just before last year's spring tour.
Horan, who became one of Australia's greatest attacking players over a decorated 80-test career from 1989-2000, said one option could be to leave one of the star flankers on the bench in an effort to develop variation and depth in what has been a troublesome position for Cheika's outfit.
"The experience Taf (Polota-Nau) has of playing over here helps us heaps in the set plays".
Australia start a three-Test tour of Europe with a game against Wales in Cardiff on Saturday, looking to continue a dominant run against their hosts and turn around a miserable run of results which has left coach Michael Cheika and his players under severe pressure.
"My main focus is to win games with Bath and be diligent as a professional every day, making sure I'm doing everything I can to become a better player", he said.
"The one thing about Australian teams, you write them off at your peril", Gatland said.
"Wouldn't it be a shame to sacrifice David Pocock on the bench?".
"From us hookers we have to take more ownership of it as well and do our work throughout the week and hit those spots then take it into the games", Fainga'a said.
The Wallabies have been going about their business diligently in Newport, about a 30-minute drive from Cardiff, while on the other side of town at Vale Resort, Wales have been fine-tuning preparations to show why that their No.3 world ranking is not fake news. "I don't think we're that far off. It's been a couple of years but I'm pretty stoked to be here", he said. I will say this is as good as I have seen us come to Europe in terms of conditioning in the last few years. I thought our fitness was off in the June series against Ireland.
"But if you look at how close a lot of those games have been, I think there's been something like seven points, the difference between us and them on average over that period".
"I've said for a number of years that the competition in the back row is insane", Tipuric said. In most test matches now there's two or three turnovers that really hurt one team.
"This will definitely be important from a confidence point of view and yes it's been well-documented that they're under different sorts of pressures than we are, but the pressure for us is being favourites and being able to handle it".
"It's a long time away, the World Cup, and there's a lot of games to go under the bridge as it were", he added.
