Oakape needs to rethink his sums! His arithmetic is probably correct but he's omitted many factors from his equation such as Annual Leave, Long Service Leave, Superannuation, Payroll Tax, assorted allowances and other on-costs.
More spin eh Ken? Annual leave, & long service leave are furphy's. At 100 hours max each month, you can still get your 900 hours in each year & have 6 weeks off for annual leave. Same with long service leave, if it isn't all taken at once.
As for Super & payroll tax, allowances, etc, that is the same for every employer out there. Sure the amounts change, as some are a percentage, but I did say "broad brush"! Always the nit-picker, eh?
