The link is for the blender you have to order (9200a), not the blender you'll actually receive. Please bear with me, this probably seems more complicated than it is.
I ordered a refurb 9200a. Received an email saying they were out of stock, and I could get either a refurb 8200 or a new 9400 at a discount. I'm told they have absolutely no refurb 9200a or 9400 models and will definitely not have any in the near future. Since the site still shows the refurb 9200a in stock, you should be given the same deal I was.
Step #1. Go to Cashrewards and search for Froothie. Maybe you'll get to keep the cashback, maybe not. Go to the Froothie.com.au site via Cashrewards, then go to the Vortex Blenders page. At the bottom there's an ad that rotates, you want the one for refurbished blenders. Click on the 9200a. Here's the direct link (paste it in the same window opened by Cashrewards):

At the moment, the Silver and Red show in stock (they are NOT). Pick one and add to your cart. Use REFURB-9200 in the voucher field to take off another $50. Shipping (for me) is $9. At this point, you should be paying a total of $358.00.
Next step, you should receive an email that includes this offer:
"We can offer you a brand new 9400 blender for an additional $60 or offer you a refurbished 8200 blender for $299 and receive a $50 refund. Please respond to this email and advise which option you would prefer."
I chose the new Optimum 9400. The $12.51 cashback is still sitting in my account, for a possible total of $405.49.
If you want the 10 year warranty, you might try your luck and pay $110 for the 10 year on the refurb 9200a and seeing if it transfers to the brand new 9400. If it works, you'd pay $528 for the Optimum 9400 with 10 year warranty vs $688 ($479 for Optimum 9400, $200 for 10 year warranty, $9 shipping). If you try it, let us know if it works.
Here's the link for the Optimum 9400 (for informational purposes only, you will not be be purchasing from this page):

Edit: I suppose it's technically possible they'd find a 9200a in the back corner somewhere, but they sure couldn't find it for me. Personally, I'd prefer the 9200a for $358. They're basically the same base model, the 9200a has pushbuttons and timers (for example, can set it to fast speed for 20 seconds), the 9400 has a dial for finer control of speed and no timer buttons.
Not a deal but a gamble
