Integrity agencies share a core function: holding public power to account.

This is important because modern governments exercise significant power, from the spending of public money, to decisions affecting infrastructure, social services, national security and economic activity. Integrity agencies provide independent scrutiny of those decisions.

Key integrity agencies include anti-corruption commissions, auditors-general and ombudsman offices. Each of these agencies plays a slightly different role.

Anti-corruption commissions investigate serious corruption and misconduct in public office. Auditors-general examine whether public money is being spent lawfully and effectively. Ombudsman offices investigate complaints about unfair or unlawful government administration.
