ALL of these are reaches due to selectivity and due to the fact you’re applying for financial aid. They’re all automatic reaches for all applicants, meaning that the regular odds for an international applicant who needs aid are about 1-3%. Since you’re very qualified, your odds increase to about 5 to 10%, but that’s still 90% odds at least you’ll be rejected. UC’s don’t have financial aid so even if you get in you’ll be unable to attend financially. Keep your fingers crossed (I assume you have back ups in Australia).
