2008 was celebrated in Australia as the centenary of rugby league football, as in Australia it was in 1908 that the code broke away from rugby. The highlight of the year was the World Cup, which was held in Australia in October and November 2008.

The first known draw in City-Country representative history since 1933, which then was 17 all.
• 9 May – The 2008 Centenary ANZAC Test took place on Friday 9 May at Sydney Cricket Ground, commemorating the first ever trans-Tasman test match which was played precisely one hundred years earlier to the day. Prior to the match the Australian national anthem was performed by singer and songwriter Julia Messenger, great granddaughter of Dally Messenger who played in the 1908 game. There was some controversy regarding the release of two Super League players, Leeds Rhinos' Brent Webb and Wigan Warriors' Thomas Leuluai as the Test clashed with the 5th round of the 2008 Challenge Cup.

Australia won their 7th straight match over New Zealand with a 28–12 win in the 9th ANZAC Test. The Kangaroos, wearing the original sky blue and maroon hooped jersey from the days before the green & gold, got out to a 22–0 lead (including a remarkably acrobatic try involving Greg Inglis and Mark Gasnier) in only 23 minutes into the match and it remained that scoreline going into the break. New Zealand scored first in the second half only two minutes in bringing it back to 22–6. However Australia put the game beyond doubt when they scored in the 64th minute regaining their margin of 22 points with the New Zealand side scoring a late consolation try finalising the score 28–12.
