simple question financia

[griddler]

Hi

Just have a quick question about applying for visa in category A
As i have read they take the lowest payslip and calculate annual income

Question is do they calculate lowest month in 6 months or do they calculate it on the lowest week paid payslip

Because i do earn over 1550 3 weeks work alot of overtime in a month and 1 week earn normal money so im hoping they take the lowest month and calculate it

Anyone shed som light please as my application is gettin processed so just wanted to know

Thanks

Also i do get paid weekly and have weekly payslips
