Net immigration numbers jump around year by year, but have been between 170K and 250K/year for over 10 years (with the exception of 2008/9 when they increased to 300K for one year)
There's been no change in policy affecting these numbers.
There have been changes in the rules affecting asylum seekers arriving by boat. In terms of numbers these aren't really significant (during the most extreme years it was around 10,000).
Separately, Australia takes in ~13,000 refugees per year who do not arrive by boat.
