Anonymous participant 774 I once made a contribution via an agent for a little discretion when a visa was cancelled. Instead of leaving country next day I got 7 days to do a border bounce :-) :-) there was another time HR asked immigration to give me 14 days rather than the usual 7 after WP and B cancelled. They were fine with that.
ScenicPersimmon526 Your common sense is correct. The MFA on their website makes it clear a visa does not guarantee entry even if they have issued it. The final say is down to Immigration. The senior MFA official interviewed at the FCCT reiterated thst point. It is there on YouTube for all to see.
