Australian Slang?

This generally means "and there you have it!" or "tada!". It's a little antiquated these days but by no means out of use. To give it a context, you would be more likely to hear "and then fold it back again, once over itself like that and Bob's your uncle - an origami swan!" rather than "keep going with the chemotherapy and with any luck, Bob's your uncle!".

Matt8_2 is right.

It may be more Cockney than Australian. I remember hearing it first while watching 101 Dalmatians. The two goons were talking about their plan, and how easy it would come to fruition. I think Austin Powers may have said it when he was speaking the English english in Goldmember.

Ask your Uncle Bob.

zanytanya's explanation is good. I believe it's originally an English rather than an Australian expression.

I say it to my daughter because I do have a brother named Bob. Dead set.

I think of `Bob's your Uncle' as a sort of agreement with something that was being discussed. Yeah, agreement!

Okay!

It's more British than Australia although it's used in Australia a lot.

It basically means "all will be well" or "simple as that"

it means that you have an uncle bob your not aware of.

All I know is, Foster's, Australian for beer.
