Perth's rookie NFL punter Mitch Wishnowsky and his San Francisco 49ers are just one win away from booking a place in the Super Bowl.
The 49ers overwhelmed the Minnesota Vikings 27-10 in Saturday's NFC divisional play-off game in Santa Clara, California.
Wishnowsky's big boot terrorised Vikings returner Marcus Sherels, who dropped two of the lanky former glazier's four punts.
Sherels' final error, off a towering 54-yard punt late in the third quarter, was recovered by the 49ers on Minnesota's 10-yard line and helped seal the victory.
San Francisco will play the winner of Sunday's clash between the Seattle Seahawks and Green Bay Packers.
The Seahawks also have an Australian punter, in former Sydney Swans AFL prospect Michael Dickson.
If the Seahawks defeat the Packers on an expected snow covered Lambeau Field in Green Bay, Wishnowsky and Dickson will go head-to-head in next Sunday's NFC championship game at the 49ers' Levi's Stadium.
Such a meeting between Wishnowsky and Dickson - both products of the Pro Kick Australia punting academy - would guarantee an Australian progressing to the February 2 Super Bowl in Miami.
The last time two Australian punters faced off for the NFC title was in 2009 when Ben Graham's Arizona Cardinals were victorious over Sav Rocca's Philadelphia Eagles.
The Cardinals went on to lose to the Pittsburgh Steelers in the Super Bowl.
Wishnowsky's four punts against Minnesota averaged 46.5 yards, with two inside the 20-yard line and a long of 56.
The 49ers' defence dominated in the second-half with the Vikings failing to score.
San Francisco's quarterback Jimmy Garoppolo connected with 11 of 19 passes for 131 yards, one touchdown and one interception.
Vikings quarterback Kirk Cousins landed 21 of 29 passes for 172 yards, one touchdown and one interception.
Elsewhere, Tennessee's Ryan Tannehill passed for two touchdowns and ran for another while Derrick Henry rushed for 195 yards and passed for a score that broke Baltimore, as the sixth-seeded Titans buried the top ranked Ravens 28-12.
Tennessee scored the game's first 14 points and led 28-6 after three quarters.
The surprising Titans will meet the winner of the Houston Texans-Kansas City Chief's game for the American Football Conference (AFC) title next weekend.
Ravens quarterback Lamar Jackson passed for 365 yards but was intercepted twice.
