Bondi, Mosman, Newtown, Ryde and Campbelltown are among the 67 Sydney suburbs that will receive the National Broadband Network by June.

The list of suburbs comes with the launch of a new online tool that will allow Australians to check what sort of NBN technology they will be receiving and when, by conducting a search on their home address.

The "check your address" function launched on the NBN website on Monday and is expected to provide greater clarity on the network's national rollout, which has been plagued by back flips and contradictory messages.

NBN is currently connecting more than 25,000 homes and businesses to the network each week, with the rollout reaching one in three Australian homes and businesses.
