Ireland v Australia
Irish fly-half Jonathan Sexton scored 16 points as Ireland edged Australia 26-23 in a thrilling and pulsating test match at the Aviva Stadium to give the Six Nations champions a seventh successive victory.
The Wallabies had stormed back from going 17-0 down within the first 20 minutes but two tries by Nick Phipps and one from Bernard Foley got them back into it.
However the Irish, unlike last year against the All Blacks when they lost in the final minute, held the charging Australians at bay for the final 10 minutes after two Sexton penalties had edged them back ahead.
Wales v New Zealand
World champions New Zealand staged a storming second-half display to dash Wales' hopes of claiming a famous victory at the Millennium Stadium.
Wales looked on their way to end 61 years of hurt against New Zealand when they led 16-15 with only 11 minutes left, but fly-half Beauden Barrett's try double either side of a Kieran Read touchdown gabe the All Blacks a remarkable 26th successive civtory in the fixture, winning 34-16.
New Zealand claimed four tries in 13 devastating minutes during the final quarter, and Wales were reduced to shellschocked bystanders.
Scotland v Tonga
Tries from Blair Cowan, Stuart Hogg, Alex Dunbar, Geoff Cross and Tommy Seymour helped Scotland settle a two-year-old score with an ultimately convincing 37-12 victory against Tonga on the plastic pitch at KIlkmarnock Rugby Park.
Scotland overcame a poor first-half performance to avenge the 21-15 defeat they suffered against the Tongans at Pittodrie Stadium in Aderdeen in November 2012, an occasion on which they conspicuously failed to cross the opposition try line.
In doing so, the Scots completed a satisfactory first home series under Kiwi coach Vern Cotter, having beaten Argentina 41-31 and pushed New Zealand hard before losing 24-16.
Italy v South Africa
Coenie Oosthuizen, Cobus Reinach and Bryan Habana provided the only tries as South Africa claimed a record 12th straight win over Italy in a scrappy 22-6 affair in Padua.
A week after a stirring 31-28 defeat of England at Twickenham, South Africa were expected to steamroller a misfiring Azzurri side following a try-less 20-18 defeat to Argentina in Genoa.
But despite finishing on a high when Habana touched over in the 79th minute, the potent, flowing game expected from Heyneke Meyer's visitors failed to materialise.
Days after being told by Springboks legend Bakkies Botha of his decision to retire from the team, Meyer said he was pleased at his side's reaction to a "very physical and tactical game".
USA v Fiji
Fiji held off a spirited USA fightback to end their November tour to Europe on a winning note with a 20-14 success in Vannes, France.
First half tries from Montpellier full-back Timoci Nagusa and wing Watisoni Votu, who also plys his club trade in France at second division Perpignan, helped the Pacific Islanders to a 15-0 half-time lead as Nemani Nadolo of Crusaders knocked over a conversion and a penalty.
