Australia host the Lions in the third and final Test on Saturday with the series already wrapped up for the tourists.
Last weekend's clash produced a thriller with the Wallabies falling agonisingly short of taking the series to a decider.
Ireland full-back Hugo Keenan's late try clinched the victory and an unassailable 2-0 lead.
There's pride on the line for the hosts but Andy Farrell has his sights firmly set on a whitewash.

The Lions stand on the verge of history with a win at the sold-out 80,000 seater Accor Stadium in Sydney on Saturday morning sealing a first series whitewash since the 1927 tour to Argentina.
They arrive off the back of two victories: a convincing 27-19 win in Brisbane and the 29-26 classic at the MCG last weekend.
While the Lions began their campaign with a defeat to Argentina in Dublin, they are targetting a first unbeaten tour since 1974 (South Africa) having won all seven games in Australia to this point.
Farrell has resisted the temptation to hand Test jerseys to a number of players that haven't featured so far, even with the main goal accomplished.
Josh van der Flier is the standout name who will finish this tour without a full cap.
Farrell (below) makes just two changes to the starting XV with Blair Kinghorn coming in for James Lowe and James Ryan replacing Ollie Chessum.
It again means that nine Ireland internationals start the game with Rónan Kelleher in reserve.
The Wallabies, who appear to be struggling to get over the officials’ call at the end of the last game before Keenan’s try, have been forced into five changes.
Star forward Rob Valetini, who lasted 40 minutes last weekend, drops out with a calf injury, while hookers David Porecki and Matt Faessler both suffered foot injuries at training on Thursday.
Flanker Tom Hooper and hooker Billy Pollard start, while Brandon Paenga-Amosa joins the bench.
In addition, Allan Ala’alatoa and Harry Potter picked up knocks last weekend and are replaced by Taniela Tupou and Dylan Pietsch, respectively.
Scrum-half Nic White gets a chance to say farewell on his final Test outing for the nine-point underdogs.
Carlo Tizzano, the replacement back row at the centre of 'The Incident' also sits out this one.
This is the 26th meeting of the teams, with the Lions winning 19 and losing six.

WHAT THEY SAID
Joe Schmidt (Australia head coach): "My belief is that 18 months ago, no one gave us a chance of challenging the Lions. [But] there's not been nearly as much between the teams as maybe people might have expected."
Andy Farrell (Lions head coach): "[A clean sweep] would mean the world to us, it's something that we promised ourselves that we were going to chase after. It's a big ask, but it's something that we're determined to do. This is the best 23 to take the group forward."
