Australia will have a representative in the Super Bowl in Arizona next month after San Francisco defeated Dallas to reach the NFC championship game against Philadelphia.
The 49ers won 19-12 in California over the Cowboys on Sunday night with Aussie punter and holder Mitch Wishnowsky playing his part.
The 30-year-old from WA is in his fourth season with the Niners since being drafted out of the University of Utah, and had four punts for an average of 36 yards - with a long of 46.
"Man, we're just excited that we won," Purdy said.
"Everyone did their part. It's playoff football, it's never easy, but we're moving on."
It sets up a clash with Jordan Mailata's top-seeded Eagles next weekend in Philadelphia
Mailata, the 25-year-old left tackle from Sydney has been with the Eagles since drafted in 2018.
Two more Australians are part of the Eagles roster in Arryn Siposs (punter) and Matt Leo (defensive end) but didn't play in Saturday's win over the Giants.
Earlier on Sunday in New York, Joe Burrow threw two touchdown passes on a snow-slicked field and Cincinnati recorded a 27-10 win over Buffalo.
Damar Hamlin's inspirational presence while watching the game from an end-zone suite was not enough to spark the Bills in Sunday's rematch of a regular-season game that was cancelled on January 2 when the safety went into cardiac arrest and had to be resuscitated on the field in Cincinnati.
Burrow completed his first nine passes for 105 yards in leading the Bengals to a 14-0 lead after their first two possessions. Ja'Marr Chase, Hayden Hurst and then Joe Mixon scored touchdowns, with Evan McPherson making two field goals in a game they never trailed.
Cincinnati advanced to consecutive AFC championship games for the first time in franchise history, and will again travel to play Patrick Mahomes and Kansas City. The Bengals beat the Chiefs 27-24 to advance to last year's Super Bowl, which they lost to the Los Angeles Rams.
Had Buffalo defeated Cincinnati, the AFC championship would have been held at Atlanta next weekend because the Bills (13-3) finished the season a half-game behind the Chiefs (14-3) after their game against Cincinnati was cancelled.
"Better send those refunds," said Burrow, who went 23 of 36 for 242 yards, referring to Bills and Chiefs fans.
"Domination from start to finish. That's what we expected. Job's not finished."
The Bengals extended their franchise-best streak to 10 straight wins and have won the past three meetings against Kansas City, including a 27-24 victory last month.
