Hi Tara, this is the brand All set that I saw at my local Bunnings a few weeks ago (I've taken to taking a photo of piggy stuff I see at the shops now, just so I can remember it better).
Not the best photo at all, but
You get 5 in a pack for $13 (well $12.95)
The other brands were ibex and rubbermaid.
The rubbermaid ones are the ones to find though as you get 12 in a pack for $25.
So I guess the answer to your question is "storage cubes".
