Are you an employee or a contractor? From among my circle of friends working for foreign companies the possible arrangements I've seen are: (a) employee of Australian subsidiary of foreign company (my situation) (b) employee, under a contract governed by Australian law, of a foreign company directly or (c) independent contractor of foreign company.

(a) and (b) give you Australian employment protections. (c) obviously only gives you whatever protections are in the contract.

I've never seen anyone under a contract of employment (rather than a contract for services) of a foreign company that purports to not be governed by Australian employment law.
