According to Section 323 of Corporation Act, auditor has the power to gain information from the audit client and the audit client must provide information or other assistance to the auditor concerning the consolidated financial statement being audit. Therefore, there is no denying that auditor would master the audit client’s business, its policies and its procedures through the information she or he obtained. Moreover, the auditor also has the professional knowledge in respect of corporate management or finance which might benefit the audit client. Thus, the provision of auditing and non-auditing services to the audit client would generate potential and real threat to audit independence.
Five independence threats are illustrated by Section 290.41 of the Code of Ethics, which are Self-interest threats, self-review threats, advocacy threats, familiarity threats and intimidation threats. The most significant threats which are created from jointly provision of audit and non-audit service would be self-interest and self-review threat. To be specific, the self-interest threat happened when an external auditor has the self-interest conflict with the audit client. For example, this kind of independence threat rises when the audit client promise to pay for external auditor in the circumstance when the external auditor provide material non-audit
