We were talking about overall PERM demand earlier, so I looked it up.
Based on receipt numbers, it is increasing steadily over the years, with the odd blip. I can only base this an annual FY PERM receipts reported by OFLC. There is no breakdown by Country for this data.
FY2009 - 60,977
FY2010 - 43,984
FY2011 - 67,383
FY2012 - 69,738
FY2013 - 72,462
FY2014 - 74,936
FY2015 - 87,644
I don't know why the number for FY2010 was so low, or what caused the sharp rise in FY2015.
