Governing the entity is the accountable authority's first duty, and the Act says what good governance must promote: efficient, effective, economical and ethical use and management of the public resources in the authority's charge, achievement of the entity's purposes, and the entity's financial sustainability. Whenever it decides something in pursuit of those ends, the accountable authority has to weigh the effect of the decision on public resources at large, not just on the entity's own. Section 21 adds, for a non-corporate entity, that governance must not conflict with Australian Government policy.
