Multifaith spaces typically imply sites where people of diverse faith traditions gather to participate in shared activities or practices, such as multifaith prayer rooms, multifaith art exhibitions, or multifaith festivals. Yet, there is a lack of literature that discusses online multifaith spaces. This paper focuses on the website of an Australian multifaith organisation, the Australian Religious Response to Climate Change (ARRCC), which we argue is a third space of digital activism. We begin by outlining the main aims of the multifaith movement and how it responds to global risks. We then review religion and geography literature on space, politics and poetics, and on material religion and embodiment. Next, we discuss third spaces and digital activism, and then present a thematic and aesthetic analysis on the ARRCC website drawing on these theories. We conclude with a summary of our main findings, arguing that mastery of the online realm through digital third spaces and activism, combined with a willingness to partake in “real-world”, embodied activism, can assist multifaith networks and social networks more generally to develop Netpeace and counter the risks of climate change collaboratively.
