The inaugural Nations Championship – a new event that has rationalised summer and autumn international rugby – is all set for its four-week finale, and it all kicks off with a tantalising Friday evening clash in Dublin.The format pits the best six nations of the northern and southern hemispheres against one another, and the autumn series begins with three sets of group fixtures before the blockbusting final weekend, hosted at Twickenham, determines overall positions.At the halfway stage, the Northern Hemisphere group remains exceptionally tight with France, Scotland, England, and Ireland all having two wins and one defeat in their logbooks. There is all to play for as they seek the top spot that qualifies for the final.The Southern Hemisphere group is a straight shootout between South Africa and New Zealand. Both are undefeated, have claimed bonus points in all three of their wins, and are well clear of their rivals in the table.Let’s see how the bookies rate the teams in this fourth weekend of action and where the money should go.Ireland v ArgentinaHistorically, the Irish hold all the aces in Friday night’s opening fixture. They’ve won all 11 of the contests between the two teams in Dublin and nine of the last 10 played anywhere.The visitors will, however, be encouraged by the last encounter – a narrow 22-19 defeat two years ago at the Aviva Stadium.Ireland v Argentina oddsHere are the latest match odds for Ireland v Argentina from bet365.Ireland: 1/3Draw: 25/1 Argentina: 12/5History is undoubtedly in Ireland’s favour, but taking Argentina with a 10 point handicap would have earned a win in four of the last six matches between the two teams.Argentina has lost to Scotland and England in the tournament, but with this handicap would have won both games – and it would have earned victories in its last three games played against South Africa and Australia.Meanwhile, if Irish coach Andy Farrell has a somewhat rookie team in play, Argentina coach Felipe Contepomi is pumped for a return to a country where he played and coached earlier in his career. Bet on Argentina to win (+10 pts) at 10/11 with Paddy Power Scotland v New ZealandThe Scots are up against it on Saturday with the All Blacks desperate to maintain their unbeaten record at Murrayfield. That strength has been emphasised by the New Zealander’s assistant coach Mike Blair, who was capped 85 times by Scotland.The visitors can also ill afford to lose points as they seek to beat South Africa to top spot in the Southern Hemisphere group.Scotland v New Zealand oddsHere are the latest match odds for Scotland v New Zealand from Sky Bet.Scotland: 3/1Draw: 20/1New Zealand: 1/4A record of two draws and 31 defeats in 33 matches will not provide Scotland with much hope – and 3/1 is not a price to get excited about as the home team tries to rewrite the history books.We will go against history in one respect, however, because a 10 point handicap would have seen Scotland win the last four autumn matches between these teams. The key difference is the new format. The All Blacks cannot afford to miss out on the bonus point and will be aggressive to the last minute. Bet on New Zealand to win (-9.5 pts) at 9/10 with Spreadex Best bookies to bet on the Autumn InternationalsHere are our top rated rugby betting sites:Wales v JapanNot much has happened to Welsh rugby in 2026 to lift its spirits. A poor Six Nations campaign compounded the problems at the heart of the nation’s administration, and the opening games of the Nations Championship did not help.There is young talent available for coach Steve Tandy, but the pressure remains suffocating for a proud rugby nation.Wales v Japan oddsHere are the latest match odds for Wales v Japan from Betfred.Wales: 2/13Draw: 28/1 Japan: 9/2Wales are in a slump and missed over 100 tackles when conceding 15 tries in the opening three tournament games in the summer. If the match stays tight, the pressure on the home side will be enormous.The last five matches the two teams have played have seen Japan win twice, and Wales sneak home by only one and three points in two other games. At this price, Japan is the call. Bet on Japan to win at 11/2 with BoyleSports England v AustraliaEngland’s coach Steve Borthwick seems to be permanently under pressure as he seeks to fine-tune a squad that has talent but often struggles to make the most of it.This week, track and field sprint star Amy Hunt has been at squad training, but will she inspire Borthwick’s outfit to shed the shackles and run free across the Twickenham pitch?England v Australia oddsHere are the latest match odds for England v Australia from Ladbrokes.England: 7/20Draw: 16/1 Australia: 23/10When playing at Twickenham, England has won five of the last six match-ups between these two teams by this margin. The current Wallabies are well capable of exceptional rugby (beating South Africa in September, for example), but they are also often poor.England has problems of their own, of course. However, this is a match-up they consistently rise to, and they need the win (and the bonus point) if they are to play the final at the end of the month.
