Okay, so I managed to get free access to the article through google (not sure if it works for anyone else but this is it, alternatively the quote also appears in fairfax publications here)... not much there to warrant a corruption enquiry as you suggest. Pollies commit to fund, defund or maintain funding all the time, e.g. Abbott's commitment not to cut the ABC, SBS, Education, Health... etc.. LOL
The Liberals live in an Age of Entitlement. They are entitled to all our taxpayer dollars... they can claim expenses the ATO would prosecute you over, but its one rule for them, and another for everyone else.
Free trips to weddings, free scholarships for their daughters not based on merit, the list of polly entitlements are endless.
I can tell you if I tried to pull the same stunt they did with the ATO, or any of my employers, I'd be sacked and in jail by now. Not for the pollies though.
