One of the big clashes this weekend will be the Aussies going to the Principality Stadium to take on the Welsh.
Australia have not had a good year at test level and they come off another hiding by the All Blacks in Japan a few weeks ago.
They lost the June test series 2-1 against Ireland, lost 3 test against the All Blacks, and once against the Springboks and Argentina in the lead up to this weekend test.
That makes it 3 wins from 10 test matches which is just not good enough.
Aussie coach Cheika has been and still is under huge pressure back home and will want to start their European tour on a winning note.
Australia do have history in their favour winning the last 13 test against Wales.
Wales got a 21-10 win last weekend against Scotland which would have helped in this weekends preparation but at the end it is what they do on the field on Saturday.
Wales will miss Warburton who retired this year face the likes of Pocock and Hooper but they have two great players in Justin Tipuric and Dan Lydiate.
The breakdown will be a huge battle.
For Wales Adam Beard comes into the starting team alongside Alun Wyn Jones at lock.
The only new face in the backs is Josh Adams who will partner with North on the wings.
Cheika have included Samu Kerevi for Australia in the midfield with Israel Folau going back to wing.
This will be another closely fought test match.
Prediction: Difficult one to call but the Aussies is not far from putting a good performance together, I give it to the Aussies by 6 points
