Oz lets in people at 44; I think that's fair.
Cutting it back to 40 would be unfair, imho.
The points system is a bit contradictory, imho.
(unless they don't really want immigrants, but are being nice to the few who pass their tests
)
They award highest points for people 29 and younger,
yet insist on 5+ years "related experience" making it obviously harder to find people under 30.
And the bulk of the workforce in places like Canada that does have 5+ years related experience
is already too old for Oz's 44-or-under skilled visa programme.
I think I saw Oz's point system and visa categories years ago and dismissed it, then forgot about it,
because at the time I didn't have that much experience or extra money in the bank.
