The Institute of Chartered Accountants says men in the profession are earning significantly more than women - and the pay gap continues to widen with time spent in the industry.
Acting chief executive Kirsten Patterson says males with less than five years experience earn an average of $3600 more than their female counterparts.
Ms Patterson said the pay gap continues to grow, becoming as large as almost $50 thousand after 16 to 20 years in the industry.
She told Nine to Noon that even firms with robust remuneration policies in place can make a small decision about pay earlier in someone's career, which can have a huge impact on parity later on.
