Wales welcome the Wallabies to Cardiff looking for their first win over the Southern Hemisphere side since 2008, losing all 12 of their subsequent Test matches.
Seven of those 12 defeats have come in Cardiff too, but Davies is confident that his side can stop the rot and believes that victory would help build momentum ahead of next year's Six Nations.
"If you look back the last couple of years, there has been disappointment after the Australia games. The advantage that the teams have coming over here is that they have just come off a tournament and been together for months," he told reporters.
"We were very close a few times [to beating Australia]. They are a quality team, you have to give them credit. They are very smart, and they take their opportunities. If you look at last year's game, they created three or four chances and they scored.
"For us, it's making sure that we are defensively all on the same page, and making sure we create pressure on them and put their skill-set under pressure. Hopefully, errors come from that. If you are too passive, these Southern Hemisphere teams just pick you off. The big thing for us is creating that pressure.
"[The 2019 World Cup] is around the corner, and a good autumn would propel us confidently into the Six Nations and help us to build momentum. We are looking for some big results in this campaign. It starts with Australia. Yes, we haven't beaten them for a long time, but with the talent we have got in this squad, we can be very competitive and get the results we want."
After Australia, Wales will also face Georgia, New Zealand and South Africa in their Autumn Internationals.
