There’s a familiar, traditional belief (popular with the kiddies) in the US that if you dig a hole deep enough, you’ll pop up on the other side of the globe, in China (ABC Evening News did a cute little feature last night, showing that you would actually come up in the Indian Ocean).
Do other children in other parts of the world have equivalent beliefs? Where do they think they would emerge?
Yes - Australia. (In reality, the closest land would be the logically-named Antipodes Islands)
When I taught English in China, I told some of my students about this idea. They thought I was friggin insane. I asked if they had any sort of similar childhood myth. The response from one student was, “If any Chinese kid thought he could dig his was to the West, we’d all have shovels right now.”
What he said.
We also heard that water swirls down a plughole in the opposite direction ‘Down Under’.
Yep. Australia for me too, or at least that’s what my mum said I was trying to do when I was dig dig digging in my sandpit. Never found Oz,: I just found a lot of creepy-crawlies. Boo hiss, sob sob.
And 
at Ravenman’s Chinese kiddies. The image of millions of kids with millions of little toy spades is quite funny.
Here in Australia, it was, strangely, China. At least when I was a kid.
I have seen postcards with a picture of kangaroos and the words “Greetings from Dublin” or “Greetings from Glasgow” printed upside down. Cute.

Sweden here, and for some reason it was China for us as well. I even remember a cartoon that was about some kids actually digging to China.
In reality, it would be in or close to New Zealand.
