On 28 July 2017, the ACCC released a final determination granting exempt service provider status to Semaphore at its port terminal facility at Osborne Berth 1, Inner Harbour, Port Adelaide . Exempt service providers don't have to comply with Parts 3 to 6 of the Port Terminal Access (Bulk Wheat) Code of Conduct.

The mandatory code on bulk wheat terminal access commenced on 30 September 2014. The code regulates bulk wheat port terminal operators to ensure that exporters have fair and transparent access to terminal facilities. The code allows for regulation to be reduced at ports where appropriate. The ACCC may exempt a port terminal service provider from certain provisions of the code in relation to a specific port terminal facility.
