Americans don't say rule like we do. I thought maybe for a second you could use pool, but I think they say that weird too. So, perfect description for Australians, but Americans are gonna still get it wrong based on the way they say the words you chose.

So maybe

Ool like in fool

Uh like in huh, that's weird

Roo like shoe

But that's me trying to think about the way Americans would say the descriptor words.
