I bet the grad student involved is celebrating now that they can finally submit their thesis
In Australia, they give you 3 years (plus an additional 1/2 year extension, which isn't always granted). After that, you're on your own, and many people get a full time job to support themselves.
I've seen quite a few people abandon their PhD because of the need to pay the bills once their funding runs out. It's quite sad.
'liberal arts' doesn't have a meaning in Australia, but I'm not aware of PhD applications being treated differently in different fields (or rather, the rules differing)
