These seem like good prices for Samsung's newest mid range tablets. Note that you need an eligible trade in device to get the $250 trade in bonus. I'd recommend going with the least value device you have eg a Samsung Watch 4 ($10 trade in value) as the trade in process can be questionable at times. I had an old iPad laying around.
You need to use the Samsung Shop App to get 5% off. I've bought lots of stuff from there but the 5% discount still applies. Screenshot of cart from Samsung Shop App
You need a .edu.au email address to register for the Samsung EDU store. No, I don't believe there is any easy way to get a .edu.au email address if you don't have one. Most school/uni students would have one, though. I assume the same prices are available in the other portals. The below prices are with a $10 trade in device eg Galaxy Watch 4.

Can you still not send in a trade in device?
