Bradtke would spend another two seasons with the 36ers before taking up a short contract with Spanish club Juver Murcia following the 1992 Olympics in Barcelona, Spain. Before he left he signed an agreement with the 36ers stating that he would finish his one-year contract with the club should he return within a certain time. Upon his return to Australia, Bradtke stated his intention not to return to the 36ers with the Melbourne Tigers rumoured to be actively chasing him. After protracted negotiations with 36ers management that led to the club being prepared to buy out his remaining contract, the NBL stepped in and vetoed the buy out, effectively letting Bradtke leave for Melbourne without the 36ers receiving any compensation for the remainder of his contract with the club. For Bradtke personally, the move to Melbourne allowed him to be closer to his then girlfriend and later wife, internationally ranked tennis player Nicole Provis. Despite playing only 17 games in 1992 in what would prove to be his last season in Adelaide, Bradtke was second in total rebounds for the 36ers to Mark Davis and in his final game for the club against the Geelong Supercats at the Clipsal Powerhouse he scored a career high 43 points and grabbed 25 boards in a dominating performance. In all, Bradtke played 118 games for the Adelaide 36ers, including 9 finals games, averaging 15.4 points, 9.6 rebounds and 1.6 blocks per game.
