The popular suburbs of Sydney, Parramatta, and the Inner South have been shockingly ranked among Australia's 'worst places to live' in a recent liveability study by health insurance comparison service iSelect. This revelation highlights a concerning trend where Australia's fastest-growing housing markets are not consistently delivering the strongest liveability outcomes. The study, which analyzed 10 key factors including income, employment, health, safety, environment, housing affordability, and community connection, revealed a grim reality for many Australians. The findings indicate that the areas experiencing significant growth in housing estates are often the same regions struggling with the biggest challenges in terms of liveability. This includes housing affordability pressure, long commute times, limited access to healthcare, and a poor work-life balance. Queensland, currently experiencing one of its biggest housing and population booms, dominates the bottom tier, particularly across fast-growing outer suburban corridors and regional centres. Several parts of Sydney's west, including Parramatta, Blacktown, and surrounding growth corridors, also appear on the list, reflecting the strain of rapid population growth in established metro regions. Melbourne and Adelaide suburbs, along with regional centres in Western Australia and New South Wales, are also among the lowest-ranked areas. The suburbs remain popular with first-home buyers and families seeking affordability, but the trade-off is a significant decline in liveability, particularly around infrastructure strain, lifestyle balance, and access to services. The 25 lowest-ranked liveability regions in Australia include Moreton Bay North (QLD), Northern Territory Outback (NT), Ipswich (QLD), Logan-Beaudesert (QLD), Wide Bay (QLD), Western Australia Outback (North) (WA), Queensland Outback (QLD), Mandurah (WA), Hunter Valley (exc Newcastle) (NSW), Sydney City and Inner South (NSW), Townsville (QLD), Adelaide North (SA), Central Queensland (QLD), Far West and Orana (NSW), Melbourne Northwest (VIC), Sydney Southwest (NSW), Melbourne West (VIC), Western Australia Outback (South) (WA), New England and Northwest (NSW), Melbourne Inner (VIC), Sydney Parramatta (NSW), Murray (NSW), Sydney Outer Southwest (NSW), Sydney Blacktown (NSW), Mornington Peninsula (VIC). The 25 best liveability regions, on the other hand, include Sydney Sutherland (NSW), Adelaide Central and Hills (SA), Sydney Northern Beaches (NSW), Sydney Baulkham Hills and Hawkesbury (NSW), Perth Inner (WA), Warrnambool and Southwest (VIC), Sydney North Sydney and Hornsby (NSW), Western Australia Wheat Belt (WA), Melbourne Outer East (VIC), Brisbane West (QLD), Bunbury (WA), Melbourne Inner East (VIC), Australian Capital Territory (ACT), South Australia Southeast (SA), Hobart (TAS), Hume (VIC), Barossa Yorke Mid North (SA), Melbourne Inner South (VIC), Capital Region (NSW), Perth Northwest (WA), Southern Highlands and Shoalhaven (NSW), Sunshine Coast (QLD), Adelaide South (SA), Sydney Ryde (NSW), South East (TAS). This study serves as a stark reminder that while Australia's housing markets are booming, the quality of life for residents in these areas is not always improving. It raises a deeper question about the balance between economic growth and the well-being of the population. As the population continues to grow, it is crucial to prioritize liveability and ensure that the development of these regions is sustainable and inclusive.
