What proportion of international students at Australian universities are studying for a computing qualification?

I am writing a paper on how Australia might do education better and I wanted to include a figure on the proportion of computer students. From the Australian Department of Education statistics I calculated that 9% of  international students in 2016 were in “Information Technology”. However, that appears far too low and I would expect 20% to 30%. Perhaps this is because it doesn't include "information systems" business students and "software engineering". Is there a better figure?
