Love Wikipedia. Awesome resource, when used for purpose. But citing it as a reliable and valid source isn't that purpose - When I'm writing new notes for the new HSC syllabus, for example, I can't cross check my knowledge against Wikipedia to make sure what I'm writing is correct. I need reputable sources so that when students read that work, I can be confident in its accuracy, because I've cross checked my knowledge against something with traceable credentials.
Edit: And that's just background reading, let alone actually direct referencing a statistic or something in a citation. Pointing to Wikipedia there would be like point to a whiteboard and being like, "Yep, the statistic is on that whiteboard there in the street! Can't guarantee no one has scribbled on it though, soz."
Not it's not. Not everything accurate in the history of himnkind has to be from a uni approved academic source.
OP has given very valid reasons for why Wikipedia is great for information searching and has numerous citations and references to back it up.
No one has actually cited or referenced anything in this thread! Citing looks like this, [1], or similar, the number in square brackets! Or do they do it different at Monash? I'm an Engineering student so not super familiar with how Law students might do it

You may resume your places, the Turtle King's rant is concluded 
Ily Turtle King <3 definitely with your initial sentiment in a lot of ways, I think people bag Wikipedia in its entirety when it can be really fantastic when used in the correct context
