10 Fastest Growing Suburbs in NSW for Property Investors in 2025

In 2025, chasing the “fastest growing suburbs in NSW” is not just marketing — it’s a data‑driven strategy. Property investors are looking beyond hype and demanding transparent metrics: price growth, population influx, rental demand, and infrastructure momentum. 

This updated guide spotlights 10 NSW suburbs showing strong upward momentum (in quarterly / annual data), especially for capital growth and yield. We’ll break down what’s fueling their rise, give you estimated metrics, and help you see which ones might suit your investment approach.

Because your mortgage partner, Mortgage Brokers Newcastle, operates in this landscape, we’ll also flag any Newcastle / Hunter / regional NSW suburbs worth watching. 

Fastest Growing NSW Suburbs 

1. Belrose (Northern Sydney / Upper North Shore fringe)

Belrose is currently topping NSW’s quarterly growth charts (29.45 % quarterly gain per Smart Property Investment). It benefits from leafy surroundings, proximity to national parks, good schools, and being within reach of Sydney’s job centres, making it appealing to high‑income buyers and investors.

The suburb is also seeing rezoning pressure and infill medium‑density proposals, adding growth impetus.

• Median house price (estimate): ~$3.1 million
  
  
• Median unit price (estimate): ~$1.2 million
  
  
• Average rent (house): ~$1,200/week

2. Mayfield East (Newcastle / metro fringe)

Mayfield East is punching above its weight: it posted ~28.79 % quarterly growth according to the same SPI ranking. It’s a strong gentrification story — near Newcastle’s CBD, with good public transport and amenities, and a rising profile among younger professionals who want coastal/regional access but still proximity to services.

• Median house price (estimate): ~$1.2 million
  
  
• Median unit price (estimate): ~$780,000
  
  
• Average rent (house): ~$700–750/week

3. Kingsgrove (Sydney’s Inner South / St George corridor)

Kingsgrove is another standout, with ~27.99 % quarterly price growth per SPI. Its appeal lies in good train connectivity to Sydney, established retail and schools, and being priced more accessibly than some inner suburbs, while still offering upside. Investors see it as solid mid-term growth territory.

• Median house price (estimate): ~$2.0 million
  
  
• Median unit price (estimate): ~$1.1 million

4. Dunoon (Outer Western Sydney growth corridor)

Dunoon is on the rise as one of the leading outer expansion suburbs, registering ~25.71 % quarterly growth per SPI. It sits in what is becoming a fast-developing corridor as Sydney’s western fringe expands.

5. Wyee (Central Coast / growth spillover zone)

Wyee is benefiting from the Central Coast housing spillover effect, with ~24.29 % quarterly growth per SPI rankings. It offers a blend of affordability, coastal lifestyle, and commuter potential (for those working in north/south corridors). As Sydney prices push people outward, Wyee is catching that wave.

• Median house price (estimate): ~$770,000
  
  
• Median unit price (estimate): ~$500,000
  
  
• Average rent (house): ~$520–580/week

Parkes makes the SPI top‑growth list (24.52 % quarterly) and represents a more regional / mixed zone play. It’s not your typical Sydney fringe, but for investors willing to look broader, it offers diversification and upside in regional NSW.
