Yours is an interesting situation. The skills assessment authority for Architects (AACA) is best placed to make the judgment as to whether (and when) the qualification meets the requirement to be considered equivalent to an accredited Australian qualification.
It would be worth doing some research on their website at http://www.aaca.org.au/overseas-qualifications-assessment/ before you invest in lodging a formal assessment application. Note that currently in Australia trained architects enter the profession with a MArch which is the culmination of 10 semesters (5 years) of full time study.
If you go ahead with an assessment, and AACA accepts the Bachelor degree, but make a judgment that it wasn't completed until Sept 2016, then this has implications for the points awarded under the general points test for General Skilled Migration visas.
Also note that currently Queensland have suspended the processing of offshore application for state nominated visas (eg 190 visa). See http://migration.qld.gov.au/
