New suburbs for The Hills

Published on 03 July 2018


Two new suburbs have been added to The Hills Shire’s LGA to support projected population growth in the north-west region. 

Norwest and North Kellyville were revealed on Friday, June 29, as the newest suburbs to join 25 established suburbs in The Hills.  

Boundaries of Kellyville, Baulkham Hills and Bella Vista were also realigned as part of the process. 

Mayor of The Hills Shire, Dr Michelle Byrne said the State Government’s gazettal of the new suburbs was a milestone that showed just how much the Shire is growing and recognises The Hills as a top “destination” for people to live, work and raise a family.

"The Hills Shire is already home to more than 150,000 residents, and with the arrival of the Sydney Metro Northwest and the development happening around our newest station precincts, we know this number is set to double in the next 20 years,” Mayor Byrne said.

“To embrace growth, manage growth and plan for growth – new suburbs were ultimately created to reflect this. It also reinforces that North Kellyville and Norwest are their own distinct communities. 

“Council worked closely with the Geographical Names Board (GNB), as well as consulted with residents, businesses and other key stakeholders over many months and will continue to work with them to make the transition as smooth as possible,” Mayor Byrne added. 

Postcodes will mostly remain the same as those previously used.  

For those living in the new suburbs or living in areas where the boundary has changed, postcodes include:

  • Kellyville suburb is 2155 and the new suburb of North Kellyville is also 2155; and
  • Baulkham Hills suburb is 2153 and the new suburb of Norwest is also 2153.

A change to postcodes for affected properties include:

  • Properties previously in Kellyville under 2155 and now located in Norwest are 2153; and
  • Properties previously located in Kellyville under 2155 and now located in Bella Vista are 2153.

Council has notified many organisations to update ‘Property or Supply Addresses’, however, these organisations cannot update mailing or billing address unless notified by the resident.

It is recommended that businesses and residents update their mailing and billing with respective organisations, including educational institutions, their employer, energy services, financial services, legal representative, Roads and Maritime Services (RMS) and anyone else they regularly receive correspondence from.

Property owners affected by these changes will receive a letter from Council with a checklist and a guide about who to notify of these changes.

Parcels delivered by Australia Post will be re-directed to the correct new address for a period of four-months (up until 31 October 2018).

When ordering products and services, Council advises residents or business owners to include a statement that their suburb has recently changed in the ‘Additional Delivery Information’ area. This will ensure the company is aware of the suburb change and will assist with the delivery of the product to the correct address.
