The nine tries scored by New Zealand is the most scored by one team in a Rugby World Cup knockout stage match. With his hat-trick of tries in this match, Julian Savea equalled Jonah Lomu and Bryan Habana's single-tournament record of eight tries.

Touch judges: Glen Jackson (New Zealand) Pascal Gaüzère (France) Television match official: Ben Skeen (New Zealand) Notes: Fraser Brown and Tim Swinson were named to start, but after Ross Ford and Jonny Gray's three-match bans were overturned, they were named in the team minutes before kick off. Matt Giteau and Stephen Moore became the seventh and eighth Australian players to earn 100 test caps. The 34 points scored by Scotland were the most they had ever scored against Australia. After the match, World Rugby issued a statement over referee Craig Joubert's controversial decision to award a late penalty to Australia. The report concluded that while Joubert could not have consulted TMO at the time, his decision was in fact wrong, as the replay showed that Australia's Nick Phipps had played the ball before Scotland's Jon Welsh received it. The correct call should have been a scrum awarded to Australia for the original knock-on.

Semi-finals This was the first Rugby World Cup where no Northern Hemisphere team reached the semi-finals. The semi-final line-up consisted of the four Rugby Championship teams: New Zealand, South Africa, Argentina and Australia. Both matches were played at Twickenham which was also used for the same stage back in the 1999 Rugby World Cup.
