He is the son of Australian former International Ted Goodwin, brother of Luke and Bryson, and brother-in-law of former South Sydney player Joel Reddy.

Goodwin made his first grade debut for Canberra in round 9 of the 2007 NRL season against South Sydney at Telstra Stadium.

Goodwin made no appearances for St. George in 2010 as the club won the premiership defeating the Sydney Roosters in the 2010 NRL Grand Final.

In 2013, after a knee reconstruction and torn pectoral muscle brought on a bout of depression, Goodwin took an off-field position with the Dragons Welfare Program to assist players with mental health issues.

In 2008, Goodwin was placed on a 12-month good behaviour bond and ordered to pay a $1,300 fine in relation to an incident at a Canberra pub.
