In 2004, Jabba participated in the Band in a Bubble project with Australian alternative rock band Regurgitator, which involved him being locked in a "Big Brother"-style environment with the group and their engineers while they produced an album under 24-hour surveillance. During this time, it was revealed that he had separated from his long-term partner and mother of his children. Following the projects conclusion, Jacquie Riddell of XYZ Networks, announced that Jabba would be taking an extended break, stating that "(the bubble) was a pretty big deal". In 2005, he left and began presenting for Nova FM in Brisbane.
