Apply for an endorsement or a student visa to study in Macao?

Both will do. According to the policy of inquiring about the Macao Immigration Bureau, both an endorsement for studying in Australia and a student visa are acceptable. Studying in Macao for more than 90 days requires a student visa. To apply for a student visa, you need to provide passport, entry permit, admission notice, proof of funds and other materials, and you need to go through the formalities before entering Macao.
