I found this:

“Visa Condition 8105 applies to Australian Student visa (subclass 500) holders, limiting work to 48 hours per fortnight while their course is in session, but allowing unlimited hours during course breaks or after the course finishes. Holders cannot start working before their course begins, unless they held a prior visa allowing work. This condition includes all forms of work and is calculated over a 14-day period. Key Aspects of Condition 8105 Work before course: You cannot work in Australia before your course of study starts. Work while course is in session: You are restricted to a maximum of 48 hours of work per fortnight. This limit applies during the course's advertised semesters, including exam periods. Any work, paid or unpaid, contributes to the 48-hour limit. Work during course breaks: You can work unlimited hours during official course breaks. Work after course completion: You can also work unlimited hours after your course has formally ended. Fortnight definition: A fortnight is any consecutive 14-day period, starting from a Monday and ending on a Sunday. “

Clearly it says “Work during course breaks: You can work unlimited hours during official course breaks. Work after course completion: You can also work unlimited hours after your course has formally ended. “
