A Queenslander has taken a brutal swipe at Sydney's cleanliness calling the streets 'putrid' and saying the city looks like 'a dump'.

The scathing assessment was made by John, a listener to Ben Fordham's Sydney 2GB radio program who rang the host to let loose on the state of the harbour city and some of its inner suburbs.

'We used to live there (Sydney) and the streets were putrid,' John said.

'Darlinghurst, Surry Hills it was all filthy. The place looked like a dump.'

John laid the blame squarely at the feet of Sydney Lord Mayor Clover Moore, who is seeking a record sixth term having been in the job since 2004.

Cr Moore announced her intention to run again on Friday.

'I don’t think it would be good for the city if I don’t continue,” she told the Sydney Morning Herald.

However, John was not impressed.

'I would have to think that Clover Moore’s a little bit up herself, being concerned that no one else concerned could do the same quality job,' he said.

'I used to live in Sydney and it really did look great but for Clover Moore to have another run, give it a break.

John told Fordham that Sydney was a 'crap hole' compared to the 'lovely' Brisbane suburb of Ashgrove (pictured refuse left by backpackers at a Sydney beach after a New Year's party)

'We stayed at Crown (casino and hotel) for three nights and Crown was absolutely beautiful until you walked out the doors and got to look a bit further into Darling Harbour and so on,' he said.

A bemused Fordham asked John where he lived and got the reply that it was in the inner west Brisbane suburb of Ashgrove.

'And it’s all beautiful there is it?' Fordham demanded.

'You know, it is lovely, it is lovely,' John replied.

'It’s not like the crap hole that Sydney looked like.'
