Conor Murray is confident that the winning mentality Ireland have forged in recent seasons can lead them to a  rare Southern-Hemisphere Test series victory this weekend.

Joe Schmidt's side face Australia in a decider in Sydney, having won in Melbourne last week after suffering a first defeat in 13 games in the first Test in Brisbane.

Since making his Ireland debut in 2011, scrum-half Murray has won three Six Nations titles, and played a starring role in this year's Grand Slam-winning campaign.

"It goes back to this team’s mentality, what this team has been through," he told RTÉ Sport. "There has been a number of Championships, a Grand Slam.

"It’s not about being over-confident, it’s just that I know this team has the ability to win a Test series down here.

"Whether it happens on Saturday or not is another thing but if we put a performance together like we know we can, there’s a high chance we’ll be in with a shot of winning.

"Australia are going to be better again than they were last week and hopefully we will too.

"We have the majority of our work done and it’s building that excitement towards a big finish."

"It makes for a cracking game."

Ireland fans in Brisbane

Murray and his team-mates have benefited from the high level of Irish emigration to Australia in recent years, with the atmosphere in the first two Tests feeling like a home game for Ireland at times.

The Limerick man is expecting the fans to give them a lift once again at the Allianz Stadium.

"There are a lot of Irish in Sydney," he said. "There are rumours there are going to be quite a few Irish (at the game), there has been already in Brisbane and Melbourne.

"Both weekends there seemed to be a stand full of Irish and we have to give them something to shout about.

"You really felt it last week. There was Olé Olé and the Fields of Athenry, all sorts of chants. They were incredibly vocal last week and that gives you a lift on the pitch.

At some point tomorrow morning, Murray will expect to be joined in the half-backs by debutant Ross Byrne, who has been named on the bench.

The Munster man likes what he has seen from the young Leinster outhalf so far.

"Ross has really impressed me," said Murray. "He’s been very calm and slipped into the group really well.

"I’ve played against him a number of times. He started for Leinster in Thomond Park when they won and started the (Pro14) semi-final in the RDS and played really well.

"Anyone who is getting an opportunity out here, they deserve it because of their form."
