Hi Taylor, I'm sorry to hear that your sister may not be granted a visa.
In this case, you could try submitting an enquiry to RMIT International via the Portal (https://rmit.service-now.com/connect, choose Services) to discuss your individual situation further. However, as your sister is not studying at RMIT herself, it may be difficult to procure an invitation for non-study-related purposes. Good luck.
