What are the likely reasons that an application might be refused?
There are various reasons why an application is refused, the least of which is the reason that your application does not meet one or more of the criteria required for the particular category of visa that you are applying for. Another reason could be that you or a member of your family does not meet health or medical requirements. Another reason could be that you provided a false or incorrect answer to one or more of the questions that you were required to answer. Another reason could be that you or a member of your family failed to meet Australian National Security Requirements. This list is not conclusive and there could be other reasons that could lead to refusal of your visa application.
