UPDATE AS OF 23 JUNE 2016:
It seems that the Australian High Commission of Kuala Lumpur has recently updated their website and it is imperative and utterly important that you visit that website and read about everything you need to know in order to successfully apply for the Australian Work and Holiday visa (Subclass 462). Please do not ask me (or the other helpful readers) questions pertaining to the application if the answers are already provided on the website or in the comments below. For goodness sake, don’t be lazy and spend some time reading the website thoroughly! If you can’t even take the initiative to even do that, then I’m sorry, we really can’t help you out. And do bear in mind that I’m not an agent nor am I working for the Australian High Commission. I’m merely an ex-Australian Work and Holiday visa applicant and can only share with you my experiences. Nothing more. If you need clarification on certain things like exemptions, translations, certifications, etc., I suggest that you email the High Commission.
