Eastwood played left wing in Hull FC's 24-31 defeat by Castleford in the 1986 Yorkshire Cup Final during the 1986–87 season at Headingley, Leeds on Saturday 11 October 1986.
Eastwood won the first of his 18 test and World Cup caps for Great Britain against Papua New Guinea in Goroka during the 1990 Great Britain Lions tour as the Lions suffered a shock 20–18 defeat by the Kumuls.
Loughlin however declined and Eastwood ultimately sliced his kick to the left of the posts.
While in Australia, Eastwood came under fan and media criticism for the amount of time he took with his goal kicks.
He played the last of his 18 tests, kicking 3 goals in Great Britain's 19–16 win over New Zealand at Carlaw Park in Auckland on 19 July 1992.
