Matera is the brother of former AFL players Peter and Wally, the third of the Matera brothers to player for West Coast. He won the club's goalkicking for the second time in 2002 and his speed and ability to apply pressure often created scoring chances. He hit back strongly after a midseason form slump. In 2003 he was in good form and won All-Australian selection for the first time after kicking 62 goals. In 2004 he just missed out on All-Australian selection after kicking 61 goals, as the selectors opted to play an extra midfielder. In 2005 injury hampered his input but he still managed to kick 39 goals from 19 games. He was a late withdrawal from the 2005 AFL Grand Final due to injury.
On 23 November 2005, Matera announced his retirement from AFL football due to a chronic back injury. He was West Coast's most prominent goalkicker for his final years in a team which struggled for quality key-position forwards, scoring 389 goals from 179 games, the second-highest number of goals in the club's history. He has since, as of December 2009, become an assistant coach at Claremont.
