It's basically the same.

Just searching "Steam Controller," minimum price $100, item location worldwide, sending to some zip code in Los Angeles (originally it was set to Germany), I get like 400+ listings, but less than 25 of the new controllers. All the others are the old ones, those Hori licensed Steam controllers, Steam Links, 3rd party controllers, flight sim stuff, etc. (I stopped scrolling after page 4, since the new controllers stopped very quickly).

Shipping from Australia makes sense (which I also see), since there seems to have been not as big of an interest there. I saw posts mentioning how they casually grabbed one, hours after launch with no fuss there.
