Australian state governments are using different methods to solve housing shortages. While New South Wales is struggling to reach its official targets, Western Australia is proposing to reduce regulations to encourage more building.

澳洲各州政府正採取不同方法來解決房屋短缺問題。新南威爾斯州正努力達成其官方目標，而西澳州則建議減少監管以鼓勵增加建築。

In New South Wales, the government is facing a large gap in the number of completed homes compared to the National Housing Accord. Between July 2024 and December 2025, only 67,502 homes were finished, which is about 46,000 fewer than the required 113,000. This slow progress was caused by economic problems, such as high interest rates and inflation, which made building apartments in parts of Sydney too expensive. Furthermore, the population grew to 8.6 million by December 2025, which increased the pressure on the available housing supply.

在新南威爾斯州，政府面臨著完工房屋數量與國家房屋協議之間的巨大差距。在 2024 年 7 月至 2025 年 12 月之間，僅有 67,502 間房屋完工，比要求的 113,000 間少了約 46,000 間。進度緩慢是由於經濟問題，例如高利率和通貨膨脹，導致在悉尼部分地區興建公寓成本過高。此外，截至 2025 年 12 月，人口增至 860 萬，增加了對現有房屋供應的壓力。

There is a heated debate in New South Wales regarding how housing data is measured. Planning Minister Paul Scully asserted that the Australian Bureau of Statistics (ABS) uses old rules that ignore student and aged care homes, meaning the actual number of completions is higher. However, federal Treasury documents suggest that changing the definition of a 'home' might be a strategy to make the government's performance look better. Additionally, industry groups like the Urban Taskforce have emphasized that there is a worrying difference between the number of building approvals and the actual number of homes being finished.

新南威爾斯州對於房屋數據的衡量方式存在激烈爭論。規劃部長 Paul Scully 主張澳洲統計局 (ABS) 使用的舊規則忽略了學生宿舍和安養中心，這意味著實際完工數量更高。然而，聯邦財政部文件暗示，更改「房屋」的定義可能是一種讓政府表現看起來更好的策略。此外，如 Urban Taskforce 等行業團體強調，建築許可數量與實際完工房屋數量之間存在令人擔憂的差距。

In contrast, Western Australia is trying to increase supply by simplifying its building rules, known as the R-Codes. The Ministry of Planning and Lands wants to reduce the minimum land size for dividing blocks from 900 to 700 square metres, which could allow for 50,000 more properties. Consequently, they plan to reduce paperwork for small projects and cut the approval time for single houses from 60 to 30 days. These changes aim to increase 'urban infill'—building on empty lots within cities—which rose to 39% in 2024, although this is still below the 47% target needed for the 2050 population projections.

相比之下，西澳州正嘗試透過簡化其建築規則（即 R-Codes）來增加供應。規劃與土地部希望將分地最低土地面積從 900 平方公尺降低至 700 平方公尺，這可能增加 50,000 處物業。因此，他們計劃減少小型項目的文書作業，並將單棟房屋的審批時間從 60 天縮短至 30 天。這些變更旨在增加「城市填充」（即在城市內的空地興建建築），該比例在 2024 年上升至 39%，儘管仍低於 2050 年人口預測所需的 47% 目標。

In summary, while New South Wales is limited by economic instability and arguments over data, Western Australia is moving toward a high-density system to increase the number of available homes.

總結來說，新南威爾斯州受限於經濟不穩定與數據爭議，而西澳州則正邁向高密度系統以增加可用房屋數量。
