Mardi

Mardi is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of 20 Nov 2025, the estimated population of Mardi is around 3,522 people. This reflects a decrease from the 2021 Census figure of 3,598 people, indicating a drop of 76 individuals (2.1%). AreaSearch's estimation of 3,536 residents, based on ABS ERP data released in Jun 2024 and validated new addresses since the Census date, supports this decrease. This results in a population density ratio of approximately 370 persons per square kilometer. Overseas migration contributed significantly to recent population growth, accounting for about 63% of overall gains.

AreaSearch employs ABS/Geoscience Australia projections for SA2 areas, released in 2024 with a base year of 2022. For uncovered areas, NSW State Government's SA2-level projections from 2022 using a 2021 base year are used. Growth rates by age group are applied to all areas until 2041. By 2041, the suburb is projected to increase its population by approximately 245 persons, reflecting a total growth of around 10.2% over the 17-year period. This projection aligns with an expected median population increase for Australian statistical areas.

Residential dwelling approval activity has been practically non-existent in Mardi

AreaSearch analysis of ABS building approval numbers indicates Mardi has had virtually no dwelling approvals in recent years.

An estimated 1 home was approved between FY20-21 and FY25-26, with none yet approved in FY26-27. Population decline during this period maintained adequate housing supply relative to demand, resulting in a balanced market with good buyer choice. Compared to Greater Sydney, Mardi has significantly less development activity, which typically strengthens demand and prices for existing properties. This scarcity is also below the national average, suggesting the area's established nature and potential planning limitations.

Mardi has very high levels of nearby infrastructure activity, ranking in the top 20% nationally

Twelve projects have been identified by AreaSearch as potentially impacting the area. Among these key projects are the Wyong South Sewage Treatment Plant Upgrade, M1 Pacific Motorway Tuggerah to Doyalson Widening project, Tuggerah Precinct Activation - Westfield Redevelopment initiative, and the Pacific Highway Upgrade through Wyong Town Centre. The following list details those projects likely to be most relevant.

AreaSearch analysis reveals Mardi significantly outperforming the majority of regions assessed nationwide

Mardi has a skilled workforce with prominent representation in essential services sectors. Its unemployment rate is 2.3%, with an estimated employment growth of 2.6% over the past year, according to AreaSearch's statistical area data aggregation.

As of June 2025, Mardi has 1,981 residents employed, with an unemployment rate of 1.9% lower than Greater Sydney's rate of 4.2%. Workforce participation is at 63.9%, compared to Greater Sydney's 60.0%. Leading employment industries among residents include health care & social assistance, retail trade, and construction.

However, professional & technical services are under-represented, with only 6.6% of Mardi's workforce compared to 11.5% in Greater Sydney. The area functions as an employment hub, hosting more jobs than residents and attracting workers from surrounding areas. Over the 12 months to June 2025, employment increased by 2.6%, while labour force grew by 2.9%, causing the unemployment rate to rise by 0.3 percentage points. This mirrors Greater Sydney's trends in employment growth and labour force increase, but with a similar rise in unemployment rate. Jobs and Skills Australia's national employment forecasts from Sep-22 project a 6.6% expansion over five years and 13.7% over ten years for national employment. Applying these projections to Mardi's employment mix suggests local employment should increase by 6.5% over five years and 13.5% over ten years, though this is an illustrative extrapolation not accounting for localized population projections.
