" through contract Labour organizations flirting the edge of employment laws and lining the pockets of owners."
Flirting is a very kind word!
You forgot flirting tax requirements also.
ATO :- Labour-hire firms and their workers. If you run a labour-hire firm you must withhold tax from payments to individual workers who perform work or services directly for your clients, regardless of whether they are an employee or independent contractor.
That then makes the Labour-hire firm liable for state Payroll Tax as applicable.
