The new growth corridor: Where smart buyers are finding value in 2025

With pricing in Sydney’s more established suburbs out of reach for many, buyers are thinking outside the box to get the home of their dreams.

First home buyers and young families in particular are turning their attention to the growth corridor of South West Sydney, where infrastructure, transport, employment hubs, and new neighbourhoods are evolving rapidly.

“South West Sydney is experiencing incredible momentum, with new infrastructure and investment driving strong growth across the region,” says Thomas Miles, Head of Sales at Castle Group.

“It’s fast becoming one of Sydney’s most connected and desirable areas for new homeowners.

A vast mix of projects, including the Western Sydney International Airport, the M12 Motorway, and the South West Rail Link Extension are in various stages of progress.

This boom is attracting many young buyers to the area, with 2025 KPMG Enterprising Cities report finding that almost 20,000 people in their 20s moved to Western Sydney in 2024.

Meeting this demand are some brand-new Castle Group neighbourhoods for residents – notably in Austral and Leppington.

“The infrastructure changes how people live and move every day, and it shifts Austral and Leppington from ‘fringe’ to a genuine growth hub with jobs, transport and services close by,” Mr Miles says.

Five new neighbourhoods to choose from

In Austral and Leppington, Castle Group is bringing to life five new neighbourhoods to give buyers a great variety of choice.

These are Bloomfield, Central Grove, Ed.Ave and Kemps Estate in Austral, and Valley Rise in Leppington.

“Leppington and Austral give first home buyers and families a chance to live in a new part of Sydney that’s being planned around lifestyle, where green open spaces, everyday convenience, and neighbourhood connection come together in a vibrant, family-friendly setting,” Mr Miles says.

Buyers can choose the perfect size of land for their needs, ranging from around 250sqm to over 450sqm, with land ready to build in some neighbourhoods.

Prices range from $659,000 to $935,000* and house and land packages start from $1.22m.*

“For young families and first home buyers, the ability to own a freestanding home with room to grow, not just an apartment, is a major drawcard,” he says.

Everyday lifestyle benefits

The South West corridor is not just enabling people to buy land and build their dream home, but also to access the range of amenities that they need every day.

“All of our neighbourhoods are positioned for everyday convenience, with proximity to schools, shops, parks and transport,” Mr Miles says.

New retail hubs, parks, playing fields, childcare centres are in the works.

Meanwhile, Austral and Leppington are also close to the Liverpool CBD, and the new Bradford City Centre.

“So, buyers see it not only as an affordable way to get into Sydney’s market today, but also as a strategic place to live or invest, where jobs and amenity are rapidly emerging,” he says.

An economic hub of the future 

Buyers interested in Austral and Leppington have a chance to get into the area before some major infrastructure is completed and demand grows.

The M12 Motorway will improve east–west connections, while the Western Sydney International Airport Metro line, and proposed South West Rail Link extension, will strengthen public transport.

“Locally, the $1 billion FAST Corridor along Fifteenth Avenue will connect Liverpool to the new airport right near where many of our neighbourhoods are located,” he says.

With new employment hubs such as the Airport, and the proposed Aerotropolis and Mamre Road Industrial Precinct on the cards, the KPMG Enterprising Cities report finds that 173,000 new jobs will be created in Western Sydney over the next five years.

“That’s what underpins the long-term amenity and growth story for Austral and Leppington,” says Miles.

Expert support for first home buyers

The five new Castle Group neighbourhoods in Austral and Leppington present opportunities for people at all stages of life, and in particular first-home buyers, to find their perfect home.

“Across our South West neighbourhoods, we offer genuine choice from registered, ready-to-build lots through to future registrations that allow purchasers to stage their finances,” Mr Miles says.

“We work with trusted local builders to provide house and land packages, which is particularly attractive for first-home buyers seeking a streamlined, low-stress path to ownership.”

Land lots in Castle Group’s South West neighbourhoods start from $659,500*, while turnkey house and land packages start from $1.22m.*
