The 2008 end of year rugby tests, also known as the Autumn internationals saw Australia, New Zealand, South Africa, Argentina, the Pacific Islanders and Canada tour the northern hemisphere. The tour ended with the traditional 'final challenge' Barbarians match, against Australia, which was the first rugby union Test at the new Wembley Stadium. New Zealand and Australia also contested a Bledisloe Cup match outside of either country for the first time; the match was played in Hong Kong with the hope of raising rugby's profile in China.
The test matches took on added significance, with seedings for the 2011 Rugby World Cup draw to take place on 1 December at stake. For the first time in the history of the Rugby World Cup, the International Rugby Board used the IRB World Rankings to seed teams in the World Cup draw. Teams will be assigned to four-strong seeding pots based on their rankings; each team within a pot will be drawn into a different pool for the World Cup finals.
New Zealand recorded a second straight grand slam tour.
