There are a number of scholarships at UWA that, whilst not solely for students with a disability, will take your disability into consideration.  On the scholarships website, select the “Educational Disadvantage” option under personal circumstances to search for Diversity, Equity and Inclusion scholarships, which includes disability.

There are also externally funded scholarships available specifically for students with a disability.  The Australian Disability Clearing House on Education and Training (ADCET) has a comprehensive list of scholarships and grants available to students with disability.
