Jozeps replaces Nick Ladd, who resigned in October along with chairman John Uhrig after struggling to end the orchestra's habitual deficits.
As the director of the National Trust, Jozeps oversaw the region's museums and historic buildings. He previously worked as general manager of the Western Australian Ballet and the Australian Dance Theatre.
The ASO has a high artistic profile, most recently playing in the pit for the South Australian State Opera's successful staging of Wagner's Ring cycle. But the orchestra has not been able to balance its budget since it was spun off from the Australian Broadcasting Company in 1997.
Jozeps told ABC Online that he would seek to increase government funding. "It's been relatively static over the last few years," he said. "The orchestra needs to develop a strong relationship with state and Commonwealth funding, give them assurances that it [the orchestra] has its house in order, to give them confidence that any increases in funding will be well used."
