Joseph Anthony "Joey" Didulica is an Australian-born Croatian former footballer who played as a goalkeeper. On 11 October 2011 he ended his career after ongoing neck and head complaints.
Didulica made his debut for the Croatian national team in a friendly match against Macedonia on 28 April 2004 in Skopje and was subsequently selected to be part of the Croatian team at the Euro 2004 finals, where he served as the second-choice goalkeeper without making an appearance. He was a member of the Croatian team in both the qualifying and finals of the 2006 World Cup, but did not play a single minute during the competitions as Tomislav Butina played eight of ten qualifiers and was replaced in the remaining two qualifiers by Stipe Pletikosa, who also played every minute in all three games at the finals. In more than two years of being part of the Croatian national team, Didulica only made four appearances in friendly matches, against Macedonia, Korea Republic, Hong Kong and Austria. Just a month after the end of the 2006 World Cup, Didulica announced his retirement from international football with an explanation that he wants to concentrate more on his club career.
