Turns out that person 1 was half right and so was person 2.
IF I get given a 1-year spouse visa I CAN'T apply for Permanent Residency.
IF I get given a 3-year (or more) spouse visa I CAN apply for Permanent Residency immediately.
The person we spoke to also said that since I had been here for 9 years already, had 1 year left on my working visa and that we had actually been married for a while, that I should get the 3-year visa straight away.
Of course, we are assuming here that person 3 knows what they are talking about as well.
What a chew on.
