Eastwood was a member of the 2008 World Cup-winning New Zealand Kiwis team and played in all of their matches, including the final victory over Australia.
Canterbury-Bankstown Bulldogs
After three seasons in Brisbane, Eastwood signed with Leeds Rhinos of the Super League for the 2009 season, however his visa to play in the United Kingdom was denied.[3] While his visa was being appealed, several NRL clubs, including the New Zealand Warriors and Canterbury-Bankstown Bulldogs, expressed interest in signing him.[4][5] He eventually signed with the Bulldogs on loan for the 2009 season.
Eastwood made his début for the Bulldogs in round 2, against the Penrith Panthers, scoring a try in the match.[6]
Leeds Rhinos
Leeds successfully appealed the decision to deny his visa to play in the UK, and Eastwood joined the Rhinos for the 2010 Super League season.[7] However, on 29 July 2010, Eastwood announced his intentions to leave the Rhinos at the end of the 2010 season, stating that he was seeking a return to the NRL for the 2011 season because he had struggled to settle in the UK.[8] In August 2010, Eastwood announced that he would be returning to the Canterbury-Bankstown Bulldogs in 2011.[9][10]
Following a season-ending tackle on Benji Marshall in week 1 of the 2015 finals series, against the St. George Illawarra Dragons, Eastwood was issued with a "concerning act" notice by the NRL, asking the Bulldogs to address his tackling style.[13]
In December 2017, Eastwood was on the way to pre season training when he claimed he suddenly felt faint and dizzy. After visiting a hospital and seeing a specialist it was revealed that Eastwood was suffering from an irregular heartbeat. Eastwood almost retired from rugby league but returned to the field in 2018.[15][16]
On 27 August 2018, Eastwood was one of the players announced by Canterbury to be leaving at seasons end after his contract would not be renewed for the 2019 season.[17]
On 23 September 2018, Eastwood was part of the Canterbury side which won the Intrust Super Premiership NSW defeating Newtown 18-12. The following week, Eastwood played in Canterbury's 42-18 victory over Redcliffe in the NRL State Championship.[18][19]
