Is NBN avaialble in new streets in Fitzgibbon chase ?

NBN roll out map says, the whole FTZ chase is NBN ready but new streets such as Flinders CCt and Otway cct are not even visible in nbn co. When i called nbn co they said, these streets are not in their database.

NBN suggested me to call any service provider and let the service provider lodge a complain about the missing address.

Apparently all this seems to be messy. Can anyone suggest and let me know if they faced same issue and have a answer.

Thank you
