Tender Details

The Tweed River Entrance Sand Bypassing Project (TRESBP) is a legislated marine sand transportation project, which operates in perpetuity. The Project was established in the late 1990s to overcome the interruption of natural sand transport to the southern Gold Coast beaches of Queensland and improve conditions for navigation at the mouth of the Tweed River. Both these aspects were detrimentally affected by the extension of the river entrance training walls in the 1960s.

Under the project legislation, the TRESBPs two main objectives are:

1. Objective for Queensland: Achieve a continuing supply of sand to the Southern Gold Coast beaches at a rate consistent with the natural littoral drift rates, and supply of additional sand as required to restore and maintain the recreational amenity of the beaches;

2. Objective for New South Wales: Establish and maintain a navigable depth of at least 3.5 meters below Indian Spring Low Water (ISLW) and 70 meters wide in the approach and entrance channel to the Tweed River; Monitoring of environmental conditions is essential in ensuring that the project meets the above objectives and also allows for a greater understanding of coastal processes which can lead to project improvements and innovation.
