San Antonio Spurs guard Patty Mills and golf’s world No. 1 Jason Day have shown their support for Australia ahead of their 2015 Rugby World Cup final clash against New Zealand on Monday at Twickenham Stadium.

Mills and Day have joined the chorus of many Australians in supporting the Wallabies’ campaign for a third Rugby World Cup championship when they face the All Blacks in an RWC final showdown. Mills, who is preparing to gear up with the Spurs for the 2015-2016 NBA regular season, has converted his teammates into Wallabies fans and has plans to turn their team room on the road in Boston into a rugby theatre to Australia.

"They were all asking me about the rules and stuff and they were pretty surprised with the big hits with no pads and everything," Mills told Fairfax Media from San Antonio. "I want to say all the very best to the boys."

Mills, who has fully recovered from a shoulder injury, posted a picture on Instagram last week wearing an Australia Gold rugby jersey to support the Wallabies in their quarterfinal matchup against Scotland. The Boomers point guard revealed he bought the Wallabies jersey at Sydney Airport before boarding the plane to San Antonio.

Day, who has regained his spot on top of the world golf rankings, also backed the Wallabies following their 29-15 semifinal round win over Argentina on Monday. The PGA Tour Championship winner posted a message on Twitter, encouraging the Wallabies to take care of the All Blacks in this year’s final RWC fixture.

Day, who just won the Australian sport’s The Don Award for his impressive golfing season, will return to the Franklin Templeton Shootout at Tiburon Golf Club on Dec. 7 to Dec. 12 to defend his title. Australian golf great Greg Norman, who the world No. 1 spot for 331 weeks, has invited Day to the event and has encouraged the 27-year-old golfer to exceed his record in holding the top spot of the golf leaderboard.

“Now I want you to do it for 332 weeks,” Norman told Day in a text message, reports the official website of the PGA. “You’ve got to keep pushing yourself, pushing yourself and pushing yourself.”

The Wallabies head into their clash with the All Blacks as the less favourite to win the Webb Ellis Cup, having beaten New Zealand just once since the RWC 2011, where the Kiwis won their second Rugby World Cup championship.
