The Australian regions outperforming the capitals for energy efficient housing
An unlikely Australian region is leading the energy efficiency charge for residential construction, while one major capital lags behind

New Australian homes are far more energy efficient than those built previously, a new report from CoreLogic has shown. The report, Amped Up: How energy efficient are Australian
Homes?’ has taken data from CoreLogic and checked it against metrics generated by the CSIRO’s RapidRate™ product to reveal that houses built after 2010 achieved a media star rating of 5.9 out of a possible 10. This compares with a median rating of 2.8 stars for homes built prior to 2010.
The most energy efficient region overall was the ACT, with a median star rating of 6.1. Within the ACT, the region of Molonglo had the highest rating. Positioned halfway between Yarralumla and Stromlo Observatory, Molonglo is the newest district in the ACT and is still under development. It is the only region nationally with a star rating of 6 or above for all dwellings.
The ACT dominated the top 30 list of most energy efficient suburbs. In contrast, Sydney and Hobart were notably absent from the top 30 list, although the report noted that there was a high level of variation across both cities. Sydney and Hobart are also the oldest cities in the country, with some housing stock dating back to the early 19th century. The report noted that demand for heating was also strongest in Hobart, which also had the lowest dwelling completion to population ratio. Heritage restrictions were also identified as a factor.
At a micro level, the Sydney suburbs of Blacktown-North and Bringelly-Green Valley recorded the highest ratings for NSW, with a median of 5.2 stars. In Victoria, the Surf Coast-Bellarine peninsula performed well, with the suburbs of Armstrong Creek, Curlewis and Mount Duneed all showing a median rating of 6 stars or higher.
Given Australian housing accounts for 24 percent of electricity use and 10 percent of carbon emissions, CoreLogic’s Head of Banking & Finance Solutions Tom Coad said it was vital that standards set in the National Construction Code were adhered to.
“The significant difference in energy efficiency between relatively modern homes and older homes can largely be attributed to changes in the National Construction Code
which has progressively placed more emphasis on energy efficiency requirements for newly built homes,” Mr Coad said.
“The Coalition’s recent push to pause the National Construction Code for 10 years flies in the face of Australia’s commitments to reduce carbon emissions.”
“Policymakers should be incentivising the construction of energy efficient buildings, not slamming the breaks.”
The report was compiled using the Nationwide House Energy Rating Scheme (NatHERS) star rating system. Research director at CoreLogic, Tim Lawless, said it was important to continue to monitor the energy efficiency of housing construction.
“What gets measured gets done,” he said. “As standards for energy efficient design and construction rise, it’s also becoming more important to measure energy resilience in
our housing stock.
“Minimum energy efficiency standards for new builds will continue to be important in supporting Australia’s greenhouse gas reduction targets, but there is likely to be
increasing focus and incentives on established housing where most of Australia’s housing stock was built prior to recent minimum standards.”

Strong population growth, major infrastructure spending and comparatively affordable property are expected to cement Melbourne’s position as Australia’s most attractive long-term real estate market.

Melbourne is poised to become Australia’s largest city within the next decade, with strong population growth, infrastructure investment and relative affordability driving long-term property demand.
A new research report from Knight Frank argues the Victorian capital remains one of the country’s most compelling markets for investors, businesses and residents.
The report highlights the city’s rapidly expanding population, diverse economy and major infrastructure pipeline as key factors underpinning future property growth.
Knight Frank Managing Director Victoria, Dominic Long, said Melbourne’s fundamentals continue to position the city strongly for long-term investment.
“Melbourne continues to stand out as one of Australia’s most compelling real estate markets,” he said.
“It is Australia’s strongest long-term growth city with the fastest growing population, the most diversified economy, world-class liveability and the most affordable major market for office, industrial and residential property.”
Population growth driving demand
Melbourne’s population has grown at an average rate of 1.8 per cent per year since 2000, faster than any advanced global economy, according to the research.
In the year to June 2025 alone, the city added about 123,500 residents, the largest annual increase of any Australian capital.
Population growth is expected to remain one of the key drivers of demand across residential and commercial property markets, including housing, offices and logistics space.
The report forecasts Melbourne’s population will overtake Sydney’s by the 2030s, reinforcing its position as the country’s fastest-growing major city.
Office market offering value
Melbourne’s CBD office market is also attracting renewed attention from investors.
Prime office rents remain significantly lower than in competing cities, with CBD office space about 46 per cent cheaper than Sydney and around 13 per cent cheaper than Brisbane.
That relative affordability is expected to drive long-term demand from occupiers and investors seeking value in Australia’s largest office markets.
The city’s office sector is also showing signs of recovery, with effective rents rising in 2025 and demand increasing for high-quality buildings in premium locations.
Industrial market benefiting from scale
Melbourne’s industrial sector continues to expand, supported by strong population growth, e-commerce demand and the scale of the city’s logistics network.
The city already hosts the country’s largest industrial market, with about 34 million square metres of warehousing stock and significant land available for future development.
Industrial rents remain competitive compared with other capitals, while Melbourne’s port handles the largest container volumes in Australia, further supporting demand for logistics space.
Infrastructure pipeline supporting growth
More than $200 billion in transport infrastructure investment between 2014 and 2036 is also expected to reshape the city and support future property values.
Major projects include the Metro Tunnel, the West Gate Tunnel, the North-East Link and the Suburban Rail Loop, which together will improve connectivity across Melbourne and its growth corridors.
Knight Frank’s Head of Research & Consulting, Victoria, Dr Tony McGough, said these investments would play a key role in supporting the city’s economic expansion.
“Melbourne is Australia’s most economically diverse city and has delivered stable growth for more than two decades,” he said.
“With strong population growth, a highly educated workforce and unprecedented infrastructure investment, Melbourne is well placed to remain one of Australia’s most attractive long-term property markets.”
