Australian state governments are implementing disparate strategies to address housing shortages, with New South Wales struggling to meet established targets while Western Australia proposes significant regulatory deregulation.

澳洲各州政府正採取不同的策略以解決房屋短缺問題，新南威爾斯州正苦於無法達成既定目標，而西澳洲則提出大幅度的監管放寬。

In New South Wales, the administration is experiencing a substantial deficit in housing completions relative to the National Housing Accord. Data indicates that between July 2024 and December 2025, only 67,502 dwellings were finalized, representing a shortfall of approximately 46,000 units against the required 113,000. This stagnation is attributed to macroeconomic headwinds, specifically elevated interest rates and inflation, which have rendered apartment construction financially non-viable in various Sydney sectors. Furthermore, a demographic surge—with the population reaching 8.6 million by December 2025—has exacerbated supply pressures.

在新南威爾斯州，政府在房屋完工數量上與國家房屋協議（National Housing Accord）之間存在嚴重差距。數據顯示，在2024年7月至2025年12月期間，僅有67,502個單位完工，與要求的113,000個單位相比，短缺約46,000個。這種停滯現象歸因於宏觀經濟的逆風，特別是高利率和通貨膨脹，導致悉尼多個地區的公寓建設在財務上不再可行。此外，人口激增（至2025年12月達到860萬）進一步加劇了供應壓力。

Stakeholder positioning in New South Wales reveals a contentious debate regarding data metrics. Planning Minister Paul Scully has asserted that the Australian Bureau of Statistics (ABS) utilizes antiquated criteria that exclude student and residential aged care facilities, thereby undercounting actual completions. However, federal Treasury documentation suggests that expanding the definition of a 'dwelling' to include such facilities could be perceived as a strategic manipulation of targets to maintain political credibility. Opposition figures and industry representatives, such as the Urban Taskforce, have noted a concerning disparity between monthly approvals and the actual completion rates required to satisfy the accord.

新南威爾斯州的利益相關者針對數據指標展開了激烈的爭論。規劃部長Paul Scully聲稱澳洲統計局（ABS）採用了過時的標準，將學生和住宅高齡照護設施排除在外，從而低估了實際完工量。然而，聯邦財政部的文件指出，將「住宅」的定義擴大至包含此類設施，可能會被視為為了維持政治信譽而對目標進行的策略性操縱。反對派人士及業界代表（如Urban Taskforce）注意到，每月核准量與滿足協議所需的實際完工率之間存在令人擔憂的差距。

Conversely, Western Australia is pursuing a policy of systemic deregulation via the proposed overhaul of Residential Design Codes (R-Codes). The Ministry of Planning and Lands intends to reduce the minimum block size for subdivision in R20 zones from 900 to 700 square metres, a measure projected to enable the subdivision of an additional 50,000 properties. This initiative is coupled with a reduction in administrative requirements for minor residential projects and a proposal to halve the approval duration for single dwellings from 60 to 30 days. These reforms are designed to increase urban infill rates, which rose from 34% in 2023 to 39% in 2024, though they remain below the 47% target for the Perth and Peel regions' 2050 population projections.

相反地，西澳洲正透過擬議的住宅設計準則（R-Codes）全面改革，推行系統性的監管放寬。規劃與土地部打算將R20分區的最小地塊面積從900平方公尺減少至700平方公尺，預計此舉將可增加50,000個物業的分區。此舉並配合減少小型住宅項目的行政要求，以及建議將單一住宅的審批時間從60天減半至30天。這些改革旨在提高城市填充率，該比率已從2023年的34%上升至2024年的39%，但仍低於珀斯與皮爾地區2050年人口預測目標的47%。

While New South Wales remains constrained by economic volatility and disputed reporting metrics, Western Australia is transitioning toward a high-density regulatory framework to stimulate supply.

雖然新南威爾斯州仍受限於經濟波動及有爭議的報告指標，但西澳洲正轉向高密度監管框架以刺激供應。
