Sim , você pode. Alto Comissariado da Austrália para a Malásia :
Can I apply if my passport is valid for less than 6 months?
Yes. However, if you are planning a short stay, it is recommended that your passport should not expire when you are in Australia. You will need a valid passport to leave as well as enter Australia. Even with a valid visa, some airlines may decline to carry passengers whose passport has less than 6 months validity. In addition, the country you are travelling to after you depart Australia may require you to have a passport with more than 6 months validity. You should check with your intended airline and/or travel agent whether it will be an issue.
