Thanks guys, its good to know that even if i don't make 25 for some reason i still have a shot 
I'm not sure if on if you'd still have a shot if you don't make the 25. The quote that Lipton gave said "Such consideration is determined by each institution in accordance with their selection policy." and the one from the Monash website seems to imply that they don't.
Probably unlikely, but it could be dodgy wording on Monash's part. Monash's one could have been referring to the idea from the VTAC quote here "You cannot be exempted from having to complete the prerequisite study."
The way Monash has said it: "the
specific prerequisites of courses for which you are applying." would imply that you need to meet the study score prerequisites too.
There's a phone number here about contacting the Admissions office of Monash,
http://www.adm.monash.edu.au/admissions/contact.html, might be worth giving them a ring and see what they say.
