Most importantly, they only need to pay ~$27/hr immediately.
This seems OK at first, as it is above the ~$25/hr minimum wage for casuals (note to non-Aussies: this figure includes a 25% "casual loading" to account for the fact that there is no sick leave, annual leave or guaranteed minimum hours).
However, this doesn't consider the fact that the drivers supply their own vehicle as well as out-of-pocket expenses for fuel, maintenance and general depreciation on the vehicle itself. When you take these additional costs into consideration, that initial ~$27 looks closer to an illegally low ~$20/hr.
The fact that they were both unpunished for finding loopholes in employment law as well as given a free pass to continue for another 3 years (despite literally being Amazon and therefore having the working capital to pay their drivers properly immediately) looks like it's a win for them.
