Why Use A Chartered Accountant?

Good question! Chartered Accountants are accounting professionals who have completed the Chartered Accountants Program mandated by the Chartered Accountants Australia & New Zealand (CAANZ).

This challenging program includes a study component (GradDipCA) plus a minimum of three years of practical experience whilst mentored by a Chartered Accountant. Following this, Chartered Accountants are admitted as members to the CAANZ who play a pivotal role in upholding the financial integrity of our society, and who represent more than 72,000 current and future professionals and business leaders.
