Okay, say you're employed in a sports team in an off-field role e.g. Chef/Physiotherapist, etc. And you go overseas to another country e.g. New Zealand. But your contract minimum wage/or Salary conditions that you signed in (NSW-Australia) is an illegal minimum wage in that country e.g. Below minimum wage of country you're working in as part of a club/or national sports team touring in that country e.g. NZ. Plus, things like in the contract about stipulations of working conditions, which may differ in the country you will be doing work in for your Aussie employer e.g. Food and safety conditions laws of NZ kitchens different to Australia laws/or Medical safe workplace laws in NZ different to Australia. Doesn't that then make all contracts that you sign in Australia (Null and void)? As when you do work in say touring sports teams e.g. ( travel to England/NZ), as these countries and many others have different, Contract law / workplace safety laws.
