Recent wildfires burning throughout Australia highlight the vulnerability of settlements located in wildland urban interface (WUI) areas. Spatial planning has a critical role in operationalising wildfire risk reduction considerations in a territorial manner across the WUI. Accordingly, more integrated approaches to wildfire management and spatial planning are necessary. However, there is limited literature examining the historical interactions between wildfire and spatial planning policy sectors and how institutions and policy instruments adapt over time to integrate mutually dependent considerations. To address this gap, this research examines how Australian spatial planning institutions and instruments evolved since European settlement to incorporate wildfire considerations, through a qualitative comparative case study approach of two Australian states. Based on the findings of the case study comparison, this paper presents a conceptual framework of the pathways towards increased policy integration of spatial planning and wildfire risk reduction that consists of six phases. It is argued that the path to greater policy integration is grounded on the development of common knowledge, a cross-disciplinary understanding, and agreed policy goals between different policy sectors, that, with time, translate into new institutional arrangements and instruments that integrate the work and decision-making processes of different sectors.

澳大利亚各地最近发生的野火凸显了位于荒地城市界面（WUI）地区的定居点的脆弱性。空间规划对于在整个WUI上以地区性方式实施减少野火风险的考虑至关重要。因此，有必要对野火管理和空间规划采用更综合的方法。但是，很少有文献研究野火与空间规划政策部门之间的历史互动以及机构和政策工具如何随时间调整以整合相互依赖的考虑因素。为了解决这一差距，本研究探讨了自欧洲定居以来，澳大利亚的空间规划机构和工具如何演变以纳入野火因素，通过两个澳大利亚州的定性比较案例研究方法。基于案例研究比较的结果，本文提供了一个概念框架，该框架包括六个阶段，这些框架旨在促进空间规划和野火风险减少的政策整合。有人认为，更大程度地整合政策的道路是建立在共同知识的发展，跨学科的理解以及不同政策部门之间商定的政策目标的基础上，随着时间的流逝，这些目标转化为新的制度安排和手段，将工作整合在一起。以及不同部门的决策过程。本文提出了一个概念框架，该框架包括六个阶段，这些框架旨在促进空间规划和减少野火风险的政策整合。有人认为，更大程度地整合政策的道路是建立在共同知识的发展，跨学科的理解以及不同政策部门之间商定的政策目标的基础上，随着时间的流逝，这些目标转化为新的制度安排和手段，将工作整合在一起。以及不同部门的决策过程。本文提出了一个概念框架，该框架包括六个阶段，这些框架旨在促进空间规划和减少野火风险的政策整合。有人认为，更大程度地整合政策的道路是建立在共同知识的发展，跨学科的理解以及不同政策部门之间商定的政策目标的基础上，随着时间的推移，这些目标将转化为新的体制安排和手段，将工作整合以及不同部门的决策过程。
