Hello, I want to go to Australia to study language for three months. I am applying for a tourist visa. Can I study language? Thank you.

Yes, generally there is a clause on the tourist visa that you cannot study in Australia for more than 3 months. As long as the language class can be completed within 3 months, it is fine. In fact, if you have a multiple-entry tourist visa per year, the length of stay in Australia cannot exceed 3 months each time.
