What does wouldn't be dead for quids mean?

Oh, dude, "wouldn't be dead for quids" is just a fancy way of saying you wouldn't miss out on something for anything in the world. It's like saying, "I wouldn't trade this for all the money in the world," but with a fun Australian twist. So, like, if someone offers you a million bucks to miss out on a good time, you'd be like, "No way, mate, I wouldn't be dead for quids!"
