John Page is a Professor in the School of Private and Commercial Law in the Faculty of Law & Justice at the University of New South Wales, Sydney.

John is a scholar of property's relationships with space, place and time in the common law tradition. His research explores the diversity of property, and how property intersects with public spaces and the materiality of place. His PhD focused on the concept of property diversity, and its implications for community, obligation, and sustainable urban design. It was published as the monograph Property Diversity and Its Implications (Routledge, 2017).

His second monograph, Public Property, Law and Society (Routledge, 2021) studies the under-surveyed, under-theorized jurisprudence of the public estate, while The Lawful Forest: A Critical History of Property, Protest and Spatial Justice (with C Clark, Edinburgh University Press, 2022), chronicles the legal geographies of spatial justice across time and space. The Lawful Forest was the winner of the 2023 Penny Pether Prize for its significant contribution to law, literature and humanities scholarship in Australasia.

John is also a co-author of one of Australia's leading textbooks on property law, Sackville & Neave Australian Property Law (Lexis Nexis12th edition 2025).
