The Shanghai Jiao Tong ones are very different indeed, the highest rank any Australian uni gets is 59 (ANU)
Lots of people were talking about this today, as you can imagine given it's a huge fall from ANU - 17 to 43! But yeah, it all depends on what criteria you use and what you think is important in a university. Another reason why you shouldn't choose on rankings alone!
Should also note that UWA isn't even in the top 200 anymore! That's not good for a Group of 8 university. But I'd say that all Australian universities are going to be disadvantaged a little because all the best ones in the country are absolutely huge and therefore tend to not have awesome student to teacher ratios.
