Unfortunatley no. Remote weddings are not legal in Australia.  The couple , the two witnesses and the celebrant all need to be present together.
What you can do remotely is:
lodge the signed and witnessed Notice of Intended Marriage with the celebrant by email
scan and email  your identity documents for the celebrant
meet with the celebrant to plan your wedding by Zoom
stream your ceremony to friends and family elsewhwere
If you need any information about the legalities of Australian marriages, always ask a celebrant listed on the website of the Attorney General's Department.
