Qf 1, firstly, I assume, you know what a mathematical constant (k) is? I'm sure you can work out how it is different in your case compared to airlines. Secondly, how about, I am allowed to bring in some 457 visa specials and open up a store next to yours paying their rates and tax? Tell me your conclusion and then talk to me about rubbish. That, I'm afraid, is our government policy!
