In Australia, how you are paid is dependent on the policy of the facility in which you work as well as your position. This can be calculated as an hourly rate or as an annual salary that is paid weekly, bi-weekly, or even monthly. Additionally, depending on where you work, you might be paid on a different day of the week or month.
According to nursingcourses.net, this can mean being paid on a Friday, or even a Monday or Wednesday. The bottom line is, it is your employer who will decide how and when you are paid, so be prepared to factor that into your planning when you embark on your nursing career.
