Vooks.net reports the games are available early for those living Down Under.
Here's how to download your games:
1 — Enter the eShop from the 3DS Home Menu. It's the icon with the bag on it.
2 — Scroll to the far left and select "Settings / Other".
3 — Scroll down and select "Titles You've Downloaded"
4 — The games will appear here once ready for download, alongside software you've already downloaded.
Europe, North America: we'll update when your games are available. For now, just cast jealous glances.
