This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
Gillieston Heights lies within the top 10% of areas nationally in terms of population growth performance according to AreaSearch analysis of short and medium-term trends
The population of Gillieston Heights is estimated at around 5,818 as of May 2026. This reflects an increase of 1,022 people since the 2021 Census, which reported a population of 4,796 people. The change is inferred from the resident population of 5,718 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 452 validated new addresses since the Census date. This level of population equates to a density ratio of 493 persons per square kilometer. The suburb's growth since the 2021 census was 21.3%, exceeding the Rest of NSW (4.9%) and the state, marking it as a growth leader in the region. Population growth for Gillieston Heights was primarily driven by interstate migration contributing approximately 79.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.
AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises the NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Looking at population projections moving forward, exceptional growth is predicted over the period with Gillieston Heights expected to grow by 4,537 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 76.3% in total over the 16 years.

Development
The level of residential development activity in Gillieston Heights was found to be higher than 90% of real estate markets across the country
Gillieston Heights has seen approximately 111 residential properties approved annually, with a total of 556 homes approved between FY2021 and FY2025. In FY2026 up to the present, 134 dwellings have been granted approval. Each new dwelling built over the past five financial years has attracted an average of 2.2 new residents per year, indicating strong demand driving property values.
The average construction cost value for these new homes is $321,000. This year alone, $50.7 million in commercial approvals have been registered, highlighting significant local commercial activity. Compared to the Rest of NSW, Gillieston Heights has 80.0% more development activity per person. Recent construction trends show an equal split between standalone homes and medium/high-density housing, offering varied entry options for downsizers, investors, and first-time buyers. This shift from the current 86.0% houses reflects dwindling development sites and evolving lifestyle needs. The area has around 35 people per dwelling approval, suggesting a growing market. AreaSearch projects Gillieston Heights to add approximately 4,437 residents by 2041.
Building activity is aligning with these growth projections, though increased competition among buyers can be expected as the population expands.

Hunter-Central Coast Renewable Energy Zone
The Hunter-Central Coast Renewable Energy Zone (REZ) is a critical network infrastructure project upgrading approximately 85km of existing 132kV sub-transmission lines between Kurri Kurri and Muswellbrook, and constructing two new substations at Sandy Creek (Muswellbrook) and Antiene (Singleton). The project delivers an additional 1GW of network transfer capacity, enabling connection of approximately 1.8GW of new renewable generation and storage. Ausgrid, as appointed network operator, is responsible for design, financing, construction and operation. The Project Deed with EnergyCo was signed in December 2025 following Australian Energy Regulator determination, and construction officially commenced on 27 February 2026. The REZ is the first in Australia to upgrade existing distribution poles and wires rather than build new transmission infrastructure. It will create 590 jobs during construction and 220 ongoing local positions, with full capacity expected by 2028.
