Homebuyers who purchase in the fastest growing suburbs of Sydney could add at least $1m to their wealth by the end of the decade thanks to land values doubling.

Growth areas across Western Sydney and The Hills District have been earmarked for the highest land value growth to 2031, sparked by huge population growth along with major investment including the Western Sydney Airport, Metro stations and infrastructure projects.

Data from Custodian has revealed Sydney’s best areas to invest both now and in the future, as well as solid long term investment locations.

Land value in Castle Hill is tipped to increase over $2.2m, while outer western suburbs of Badgerys Creek, Austral and Greendale could rise over $1.2m by 2031.

According to the data, land values in suburbs of Mulgoa, Luddenham and Orchard Hills will increase over $1.5m while Macquarie Park and Marsfield will exceed land values of $3m.

Suburbs identified as good investments both now and into the future were southwest Sydney’s Cobbitty and Leppington and northwest areas of Rouse Hill, Beaumont Hills, Riverstone and Marsden Park.

Custodian’s property investment expert James Fitzgerald said Sydney had already seen a lot of growth however also “picks up the lion share of overseas migration”.

“We like the Hills region which has benefited significantly from the NSW Government’s investing in the metro, adding eight new stations and five upgraded stations in recent years,” he said.

“Longer term, it’s hard to go past the outer west in and around Badgerys Creek where the

NSW Government is building the new Western Sydney Airport. This is a $5.3 billion infrastructure project that will support 14,000 jobs during the construction phase alone.”

At the age of just 19, savvy investor Joel Goh has honed in on two of Sydney’s growth areas.

The student and construction worker recently sold an investment property in St Marys, making a healthy profit after owning the home for just 10 months.

“I chose the area due to the huge growth around the airport and Metro,” he said.

“The entire area is going to gentrify with professionals and young families. Land is scarce as well which is why I bought a larger block.

Joel Goh's investment in St Marys sold in November 2023, making a healthy $400K plus profit.

“I got into the market in January when everything was at its bottom and decided to sell now as things have started to rebound. We had great competition at the auction with 10 bidders.”

Mr Goh is using his investment profit to buy an off-the-plan apartment in the Hills District suburb of Norwest.

“The area has had a huge amount of infrastructure,” he said. “It’s a great area for capital growth with the Metro Station, you will be able to get to the city in 35 minutes. They are building a new commercial centre around the station which is bringing another 10,000 jobs.

“The thing about the Hills is it used to be considered an area far from the city where you had a big family and connectivity was scarce. That’s not the case any more, you can enjoy the greenery and still be close to the city.”

He said he was also on the lookout for another investment in and around St Marys.

Mr Fitzgerald said the key to selecting the right location for investment was finding areas with

growing populations, with houses generally better investments than units.

“Houses come with land and land is what appreciates in value, while physical buildings actually depreciate from the moment they are finished,” he said.

Mr Fitzgerald said all of the locations he recommends were surrounded by multiple job hubs and have good existing and future planned infrastructure.

Ray White Diamantidis Group principal Peter Diamantidis said cases like Mr Goh’s were more common in the St Marys and surrounding areas with investors attracted to the new Metro and growing infrastructure.

However, he said the area was still attracting first homebuyers who are able to get into the market around the $800,000 mark.

“Once the Metro is finalised you can be in the city in 48 minutes,” he said.

“And you will do well into the future, this area is not stopping with the Metro, airport and big companies basing themselves here such as Amazon and ALDI.”
