Australia tourist visa is not extendable. You need to apply for a new visa for a longer stay. Applications for visa are processed in time but it may get delayed if your form is not properly filled or it does not have all the required documents. If your documents lack authenticity then also your application will be rejected. An Australian visa is digitally linked to the applicant’s passport. Thus you will not get a label in the passport. Another thing which is checked before granting a visa is that you have enough money for sponsoring your trip to Australia.
