I assume she came on a tourist visa. She should've applied for family visa, but having Googled, a parent visa can take up to 30 years to process
This sounds promising though:
It says in the article it is up to 30 years. The thing is the family are going to bring her bac to Scotland despite saying earlier that she isn't well enough to fly. Their arguments don't quite work.
I think that the family may well have taken some liberties with how they got mum there in the first place. Whether legitimate mistake or not, I does
sound like a good case for mercy. I'd have considered the trip to Vanuatu would have fulfilled the requirements to leave the country, but, I've not
investigated the act in regards visas. Mum may well be in no condition to travel alone, with a family member accompanying she might be ok. So, mary,
the apparent inconsistency might be explainable.
This looks like another stuff up by pollies, who modified the act a couple of years back to make it easier to deport undesirables, but it did have some unfortunate side effects. One bloke was deported for a criminal act (not particularly bad IIRC) despite having lived in Aust since he was a young child. His parents never bothered to naturalise him, and, the govt were certainly very happy to take his taxes and let him vote, along with, I believe, receiving benefits from the same government. I think he was also married with kids who, of course, were not deported.
96 is 96. She is old.
She'll probably be OK on the flight, but it will be really tiring, unless, of course, she gets upgraded to business or 1st class
