The E3 visa application fee is $205USD ($287AUD). This is much cheaper than many other visas because there is no additional cost down the road when you actually get approved. Many visas have an issuance fee after the application fee, but that's not the case with the E-3. More importantly though there is no cost to the employer. This application fee can be paid by you or the employer, but there is no other work that is required which makes it a much lower barrier than many other visa options available to other international citizens.
