Abstract: A critical analysis of the campaign by Jake Cassar and the Coast Environmental Alliance (CEA) to revive Old Sydney Town, a defunct colonial theme park in Somersby, New South Wales. While promoted as a grassroots heritage project, the revival effort reveals deeper settler-colonial investments in cultural mimicry, identity fraud, and the erasure of Aboriginal authority. By tracing Cassar’s affiliations with conspiracist and settler-spiritual groups, examining rezoning politics, and analysing media complicity through Coast Community News, the article uncovers a pattern of cultural re-entrenchment that weaponises nostalgia against truth-telling. Grounded in Indigenous critique, heritage studies, and media analysis, this article argues that the Old Sydney Town campaign exemplifies the white possessive logic described by Moreton-Robinson (2015), and must be understood as part of a broader movement to undermine Aboriginal sovereignty and reassert settler control through aestheticised colonial memory.
