Residents in Sydney's inner west and south have been urged to sign a petition calling on the government to “fix the mess” of the national broadband network after delays left locals without a date they could expect to switch.

Anthony Albanese, the federal member for the Grayndler electorate, launched the online petition on January 2, urging the government to “give us our NBN” and slamming the delays.

Twenty-one per cent had the NBN but were unhappy with it.

Within two days, 650 people had signed the petition. Of those, 53 per cent said they did not have the NBN but wanted the service.

Another 21.3 per cent had the NBN but were unhappy with it, and 2.6 per cent had the NBN and were happy with it.
