there's also possibility that your listed refs throw u under the bus with a lousy reference check, u can more or less suck thumb and kiss good bye.

from personal experience (having gone the other extreme of provisional offer retraction after clearing G50 and clearing submission with Perm Sec for the formalisation of provisional offer), the hiring SB/Ministry usually will await the outcome of the admin checks (ie no red flags in the G50), good to go then put up submission papers for Perm Sec approval to formalise the job offer.

from organisation perspective, it will take a very brave soul to put up submission paper to seek PS approval to hire a potential candidate that didn't pass the admin clearance phase.
these senior civil servants are super sharp ones, cannot hide from them.
