Visitor visa to Prospective marriage visa -conditions to get married

I entered Australia on tourist visa in 03/2025 and then granted my 300 prospective marriage visa on 08/2025 (already had this visa applied when I entered Aus).

Can i now marry my partner or do i have to leave Australia and then come back into the country to marry? Do i need to leave Australia to marry my partner if i am on prospective marriage visa because I entered Australia on visitor visa? Question on partner visa application form is what got me confused: please help.

Q Did the applicant marry the sponsor after the applicant's first arrival in Australia as the holder of a Prospective Marriage visa?
