Some good deals at the Lenovo education site. Free shipping.
You'll need access to a .edu.au address (your kid's), or contact them to "verify" (send photo of your kid? :-) I'm sure they don't make it hard.) You can use your regular email address after that.
This well-spec'ed C340 at $746 looks good for school, if you like a big screen 2-in-1 with pen.

Definitely not an ultralight though.
