Was looking for a bike storage solution that didn't involve drilling walls, and bumped into that at Google Shopping. Looks like a good deal; Kogan sells a different model for $35 ($30 for prime subscribers), and other stores charge $60-70 for it. The pics on the Bunnings don't show the bike in the vertical position, but this store on eBay does.
Update: I bought 3; details below.
