I respectfully disagree. Fast track degrees often provide the same modular length as regular degrees. For example, I did a Mass Communications degree from OCU (under MDIS.) I did the full number of modules a student at the actual american campus at OCU would have done, but in half the time. This is because of the course structure that allowed me to complete my degree module by module, which I frankly enjoyed because it meant I only had to concentrate on one subject at once, instead of worrying about "exam week" and having to study for 5 different subjects at once.
What I'm trying to say is that my degree was done more quickly, but it was in no way inferior to a degree obtained through the actual University; my teachers were all staff from America flown in to teach each module, so even then I got the benefits of an overseas degree while studying in Singapore. Even if you study in Australia, a lot of their degrees can be completed in a year or two and I don't think they are seen as being inferior degrees. How desirable you are on your resume depends on a lot of other factors, such as doing internships or having prior work experience. Some of my classmates find it difficult to even get a job interview, while others get offers coming out of their ears, despite having the same degree.
I would recommend going down and speaking with the school consultants to find out more. Also, my personal opinion as an MDIS student is that it was a surprisingly pleasant experience doing my degree with them
