For those who may be interested here are some links to booklets on migration trends to Australia from the DIBP website. Interesting to compare the 2010 report to the current 2017 report. A wealth of data in visa classes, countries of applicants, skills, changing and consistent trends, etc. For example the number of partner visa grants have been virtually identical for the last 5 years, and grew only slightly over the 5 years prior.
