Well, in Australia, the average salary for the same job role can be different in different states and provinces. Even though other things, like training, also affect a casual worker's pay. But the most reputable websites, which got their information from anonymous employers and workers from all over Australia, say that the average wage for a Food Production Worker is between $16 and $17 per hour. So, based on these numbers, a monthly wage of $16.40 is fair and in line with the most recent wage norm.
