This is a brilliant newspaper correction, printed in Australia's Morning Bulletin:
It is a little surprising that the reporter didn't think to check. "Crikey, that's a lot of a pigs mate, are you sure you mean 30,000?". Similarly, if they really thought there were 30,000 pigs floating down the river, why did they only put it on page 11? That would be Biblical!
