It's important for Wales the finish their year off with a win to give them some confidence ahead of the Six Nations.
Wales need to win to give everybody a bit of hope but it will be tough.
Australia will be hurting having lost to Scotland and England over the last fortnight. It's tough to call this one.

The countdown is over.
The referee Mike Adamson (SRU) blows his whistle and James O'Connor gets us under way in Cardiff.
Which side will end the year on a high?

Maybe these rugby fans have heard rumour that Hen Wlad Fy Nhadau has been sung better at Cardiff City Stadium at the recent football internationals.
Well they've raised their game and their voices today.
That was hair-raising stuff from the near capacity crowd.

The ex-Wallabies wing says the absence of captain Michael Hooper will be a big miss for Australia.

Those flame-throwers are seriously strong. I think they might have toasted my eyebrows.

It's been an interesting few weeks for Manchester United fan Dan Biggar.
The Wales fly-half enjoyed dinner with Usain Bolt and Sir Alex Ferguson after watching his side play at Old Trafford.
The mounting pressure on manager Ole Gunnar Solskjaer is one that resonates with Biggar, he too has had to win over the doubters.
"I don't know why he [Solskjaer] bothers doing his job, as he's got 10 million people who think they can clearly do it better than him," said Biggar.

Head coach Dave Rennie says Australia are "desperate" for victory today.
They've lost both their matches in Europe this autumn, against England and Scotland, so they'll be aiming to end their tour on a high tonight.
"They [Wales] have had a couple of losses and found their way past Fiji on the weekend," said Rennie.
"We’re pretty desperate as well.
"We haven’t performed as well as we’ve needed to in the previous two Tests and we’re keen to make up for it.”

Wales centre Nick Tompkins says the players "desperately" want to finish the autumn series on a high.
Defeats against South Africa and New Zealand were followed by an unconvincing win over 14-man Fiji.
The campaign has been ravaged by injuries and Wayne Pivac has used close to 40 players so far.
And while Tompkins says the influence of missing players like Alun Wyn Jones, Taulupe Faletau and Justin Tipuric is " immeasurable", it's been "nice to see other lads stepping up".

Wales and Australia have forged quite a rivalry in recent years.
It seemed one-sided for a time with the Wallabies winning 13 matches in a row from 2008 to 2017 - but only two of those victories were by more than nine points.
Wales avenged those narrow defeats by beating Australia here at the Principality Stadium in 2018, and they followed it with an exhilarating win in their 2019 World Cup pool match.
Considering the two sides' form coming into today's game, you wouldn't bet against another thriller.
