Accountability is the price of statutory independence, and the price is considerable, especially for the kind of editorial and creative independence exercised by the ABC and SBS. As the Australian National Audit Office once observed dryly of the ABC, a national public broadcaster is subject to "more diverse" expectations of accountability than a private sector operator driven principally by the need to achieve a commercial profit. Having offered this self-evident truth about the national broadcasters, the Audit Office was silent on the reciprocal accountability of government.
