Fronted T4 with UK docs, partner has AU only. No signage, so I do the decent thing and queue in the strangers bar. 45 minutes pass we get to front:
"oh, next time you can both use the EU passport lane"
But there is no signage. How can you know? You would feel like a complete queue jumping twonk to ask, but why can't they say "...and accompanying partner/spouses" on the signage?
As for "pay GBP70 if you do this more than 4 times in the last 3 months with two partridges and a quarantine approved pear tree and we *might* let you in expedited" .. please. No. don't charge to speed up. Speed everything up and we all win.
The oddy? You can (I believe) now use US and UK biometric passports in the AU/NZ readers. No reciprocity. As my partner said, if the did, they'd have to let the rest of the commonwealth in and that would be .. common.
