Okay, let’s tackle this. So Tegan has 17 years of experience as a Chartered Accountant, which is a significant amount of time. Her skills in tax, accounting, and financial management are in demand. Location is Canberra, Australia, which is a relatively stable and secure market. According to the Australian Institute of Chartered Accountants, the average hourly rate for a Chartered Accountant in Canberra is around $120-$180 per hour. Considering her experience and skills, I estimate her hourly rate to be around $120, which is on the lower end of the range. However, this is a reasonable estimate based on the available data.
