Found this baby bungee platform for $79 at Harvey Norman with an extra $12 for delivery.
That's pretty good compared to CatchOfTheDay or Scoopon who has the Bounce Bounce Baby on sale for $119.99 with an extra $9.99 for shipping. I've also found it on babyco.com.au for $89.95, but you have to email to arrange for shipping & costs, so it seems complicated due to the small scale their business has.
Fishpond sells it for $1599 (I'm not kidding http://www.fishpond.com.au/Baby/Bright-Starts-Bounce-Bounce-Baby-Activity-Zone/0074451071223)... wtf?!
So basically it comes down to $91 delivered at Harvey Norman vs. $129.98 at COTD / Scoopon.
