I thought I might be able to fill in a few gaps here:
Somewhere around the middle of 2013 the Australian Quality Frameworks did an assessment that lead them to the decision that a Graduate Diploma of flying was not on par with other Graduate Diploma studies, so they advised the relevant government body to discontinue providing FEE HELP payments towards all Graduate Diploma of Flying units at all universities across Australia at the end of 2014. This is where the deadline has come from.
There will, however, be some flight schools and other RTOs who will be able to access similar government funding options moving forward. I believe both ACFT and the RACWA are both included in this.
