A NSW government Minister has declared Adelaide "boring" and Canberra even more so.
The comments were sparked by advertisements urging frustrated Sydneysiders to avoid gridlocked roads by moving interstate.
Roads Minister Eric Roozendaal dismissed the recent ad campaigns backed by the South AUstralian and ACT governments, which targeted users of Sydney's problematic rail network and its congested roads.
"The South Australian government can do whatever it wants," Mr Roozendaal told reporters in Sydney today.
"But anyone that ... has been to Adelaide knows it is a pretty boring place, and it just can't compare to Sydney.
"Anyone who goes to Canberra knows Canberra is even more boring than Adelaide, and Sydney is the greatest city in the country."
Some of Sydney's major train stations have been plastered with billboards reading: "You'd be home by now if you lived in Adelaide".
It follows a similarly themed campaign targeting the city's often frustrated motorists in which a rear-panel advertisement on buses read: "Like traffic that moves? Move to Canberra".
