Project Background

Townsville City Council is responsible for maintaining the canal sections in Nelly Bay Harbour. Council's last major maintenance dredging campaign was undertaken in 2011, with smaller scale sidecasting works subsequently carried out in 2021, 2022 and 2023 respectively to manage sediment build up. The works provided temporary relief for vessels using the marina berths.

Recent hydrographic surveys show that maintenance dredging is now required remove accumulated sediment from the marina and return the canal sections to their original design depths.

Dredging was scheduled for early 2025 but postponed so Council could prioritise urgent road and bridge repairs following severe rainfall events.

Project Overview

Since early 2025, Council has been reassessing options for the placement, treatment and management of dredged material from the proposed maintenance dredging works.

The currently approved option is to use Council’s site at 55–77 Kelly Street, which has the necessary approvals and permits in place. However, community feedback has highlighted concerns from residents, and Council has since been investigating alternative approaches for managing dredged material.

As part of this process, Council explored sea placement as a potential alternative and has undertaken consultation, technical investigations, environmental assessments, and stakeholder engagement to support assessment of a Sea Disposal Permit application. Council is currently awaiting further advice on the permit application.

Maintenance dredging is expected to proceed once all required approvals are in place and a suitably qualified contractor has been engaged through Council's procurement process.
