Massey definitely had some form of agreement in 2000ish with regards to Singaporean students. As I recall it was based on the students average marks over the course rather than just the top 10.
Massey has had it's fair share of people bagging it over the years but it does a good job of training what it gets. As with most organisations there are a few knobs around.
I'd do what 058 says and contact Massey and more importantly SIA to get the real story.
Good luck.
