A quality audit is an audit conducted by a competent and independent auditor. Competent auditor means having accounting, auditing, and information technology knowledge. Independent auditor means feeling free from conflicts of interest with any related party. Apart from competence and independence, many factors that affect audit quality should explore. This study examines the effect of good corporate governance effectiveness and auditor quality on audit quality, with the auditor as respondents. The auditors were selected based on the purposive sampling method, with the criteria of working in a Public Accounting Firm registered in the IAPI Directory and residing within the territory of the Republic of Indonesia. The results confirmed that work experience, competence, integrity, objectivity, and professionalism positively affect audit quality. However, independence does not affect audit quality. Accountants, a profession that works based on stakeholder trust, require a competent, integrity, and impartial person who is full of ethical dilemmas in the process of his work. The low competence will significantly impact audit quality and the economy. The inability of auditors to maintain public trust by opportunistic actions, ignoring norms and morality has an impact on the credibility and legality of the accounting profession.
