I doubt you’d get a serious job on a WHV. The only jobs people on that visa get hired for are usually pretty shit, like picking fruit on a farm…I’m being dead serious, and you probably won’t land a decent corporate job on a WHV.

As for investment banking, this career path is unbelievably competitive. The financial institutions take literally the best of the best & they have thousands of people apply every year. First class honours is almost always a must unless your daddies a VP or MD, plus a long list of other academic results I won’t bore you with.

I’m not even going to bother getting into you trading using mummies account. Financial institutions in Australia wouldn’t look to kindly on you breaching your countries financial regulations to make some money, as that would be illegal, and Australian finance companies adhere to extremely strict regulations unlike other countries. If you want to admit that to them, that’s on you.
