The Nations Championship is the most ambitious cross-hemisphere competition rugby has ever staged, and South Africa are already making their presence felt. The Springboks hammered Wales 43-0 on 18 July 2026 — a statement of intent that sets the tone for what is shaping up to be a compelling southern hemisphere title race.
The competition pits the six Six Nations sides — England, Ireland, Scotland, Wales, France and Italy — against southern hemisphere powers South Africa, New Zealand, Australia and Argentina, with invited sides Fiji and Japan completing the 12-team field. Yes, Japan sits roughly 2,500 miles north of the equator, but rugby is rolling with the geography. Fiji, meanwhile, are staging their home fixtures in the northern hemisphere to ease logistics and maximise revenue.
The format is straightforward. Every team plays each of the six sides from the opposing hemisphere once, split across three rounds of fixtures in July and three more in November. Results rank teams within their own hemisphere — one through six — setting up a climactic three-day playoff event at Allianz Stadium, Twickenham, on the final weekend in November.
Those playoff matchups mirror the standings: sixth-place North against sixth-place South, fifth against fifth, and so on, until the two top-ranked sides meet in the final. The winner of that match is crowned the inaugural Nations Championship champion — a title that carries genuine weight given the quality assembled across all 12 teams.
