up the bush

I know you've been waiting all day for an answer, but I had no idea what this meant. I've never hear it before. Up the creek, yes. In the weeds, yes. But not this. Usually I wouldn't write just to say "I don't know!" but you've had no responses all day, and perhaps that's because this phrase is as unknown to others as it is to me.

Some context (link?) would help.

Hi,

I wonder if perhaps this is part of a sentence about George Bush that you are taking totally out of context?

eg, from the NBC website: That sums up the Bush administration's Iraq-style "reconstruction" at home

We await your context, to clarify this.

Best wishes, Clive

Thank you, Barb, Marius and Clive,

In fact, there's no context with this phrase. Because I found it

in a learning material written by a nonnative speaker of English.

I don't know from where the author took this expression.

But I think it must be a mistake.

Thank you again for your help.

Regards,
