Rottnest Island Thomson Bay Boating Ban Extended to 2027 for Major Construction
The Rottnest Island Authority has signalled a significant, long-term closure of Thomson Bay to all boating activities, extending well into 2027.
What happened
The Rottnest Island Authority has issued a Temporary Notice to Mariners, officially closing waters in Thomson Bay to boating from June 15, 2026, to November 30, 2027. This extended closure is to facilitate the construction of a marine logistics hub. The notice, published in the WA Government Gazette, outlines the full extent of the restricted zone and the duration of the closure, impacting a critical area for island access and operations.
What this means for you
If you're a recreational boater planning a trip to Rottnest Island, your access to the popular Thomson Bay will be severely restricted for over 17 months. This includes charter operators, fishing enthusiasts, and day-trippers relying on their vessels. Commercial marine tourism operators face significant disruption, potentially needing to reroute services or seek alternative berthing arrangements. Businesses on Rottnest Island that rely on direct marine access for supplies or customer drop-offs may also experience logistical challenges. For those involved in marine construction or logistics, this project presents a significant contract opportunity, but also demands careful planning due to the extended timeline and remote location.

What this means for WA
This closure signals a substantial investment in Rottnest Island’s infrastructure, prioritising long-term operational efficiency over immediate recreational access. It reflects a broader trend in Western Australia of developing critical state assets, similar to the ongoing developments outlined in the Westport Bill 2026, which aims to reshape Fremantle's port infrastructure. The decision highlights the WA Government's commitment to upgrading key facilities, even at the cost of temporary public inconvenience. The timing, spanning two summer seasons, will undoubtedly test the patience of many West Australians who view Rottnest as a vital recreational escape.
The numbers
The Thomson Bay closure is set to last for 534 days, commencing on June 15, 2026, and concluding on November 30, 2027. This extended period underscores the scale of the marine logistics hub construction. The Rottnest Island Authority, the entity responsible for this notice, manages one of WA's most iconic destinations, drawing hundreds of thousands of visitors annually. While specific visitor numbers for Thomson Bay alone are not detailed here, the bay is a central hub for tenders, ferries, and private vessels, indicating a broad impact. For comparison, the Taxation Administration (Land Tax Relief - Cyclone Narelle) Declaration 2026 covers relief for two financial years, highlighting different scales of government intervention. The Shire of Toodyay Dog Local Law 2026 demonstrates the diverse range of local regulations GovScanner tracks.
