Đolonga started his career at his hometown club Hajduk Split. In the 1994/1995 season, he was loaned out to NK Uskok, that won the Druga HNL. However, he got injured and Hajduk did not want to offer him a senior contract. He moved to Solin Građa for the 1995/1996 season, and in the 1996/1997 season made his Prva HNL debut with NK Orijent. The following year he moved, this time to Hrvatski Dragovoljac, where he played 87 games in three seasons before moving to Spain to play for Deportivo Alavés. After playing just three games, he returned to Croatia to play for Hajduk Split. After his contract ended in June 2007, Đolonga joined NK Mosor, but decided to retire from football in September 2007, after playing just two games for the club.
