Ten did try it about thirty years ago, but it was on the old dollar values (before the US version doubled them) and even then the values were squibbed a little. Probably similar state to when Seven did Press Your Luck, the values won were more like mid-four figures than consistently five. Of course, you can’t get away with that too much in Australia anymore, and I don’t think you could do a local daily Jeopardy! on a $5-10k per ep average prize, which is what the likes of Ten would likely need to jump into it.
On the other hand, the Fry version is not a daily version either, it’s a 1-hour format, with a “Triple Jeopardy” round of sorts added - so once? twice? weekly, I guess. Presumably Ten would be the faves to get the Australian episodes of those, given Paramount own the format rights to Jeopardy! .
