In saying that, I need to read up a bit more, but if I can get the Nexus 5X 16GB for $200 or 32GB for $250 like is mentioned in the article/comments below without actually using Fi, I may just jump on it for that!

Depending if the discounted price applies to Australia ($150 off making it $400 or 32GB I believe), then you should be able to just buy it and activate Fi for a month then cancel it again.
Doesn't look like discount available to Australians. Unlucky I guess.
