Is there a pay increase between undergraduate and MBA students?

In 2020, the Australian Government Department of Education, Skills and Employment Graduate Outcomes Survey found that working professionals without a postgraduate degree received a median salary of $64,000 per year, while those with a postgraduate degree in addition to their undergrad degree earned on average $98,000 per year. The Australian Financial Review reported in its 2019 MBA Rankings that Australian MBA graduates see an average salary increase of 28 per cent to reach $157,000 within three years of completing their course.
