Channel Seven's political reporter Alex Hart got a bit hot under the collar on a weekend trip to Perth, claiming the city is "the worst city in Australia".

The popular Canberra-based reporter took to Twitter last night to offer some feedback to the world's most isolated city.

"Perth. "The worst city in Australia". #justsayin," he posted to his 3,485 followers.

Channel Ten's political chief and fellow press gallery cohort Hugh Rimington quickly chimed in, "Better get outta town quick, Mr Harty."
