As someone who has gone through the Melbourne Model, I don't know if I'd call the semester's worth of breadths in the BSc "liberal arts rounding" in the same sense as people are using it here, mainly because it's a free choice of subjects outside your degree (and most subjects are available). E.g. it's not uncommon to take management subjects as an "employable" breadth.
