1. Purpose

To advise members, the GTA Board has approved the release of the 2026-27 GTA Location Differentials (LDs) for South Australia (SA), as recommended by the GTA Commerce Committee. These are now available on the GTA website and will take effect from 1 October 2026.

2. Background

GTA publishes the LDs for the storage locations of our members in QLD, NSW, VIC, SA and WA annually to enable participants using the GTA Contract No. 2 Grain and Oilseeds in Bulk – Basis Track to price grain at up-country sites. Each year GTA consults with members and the wider grain industry to address potential changes.

With endorsement from the Commerce Committee, the GTA Board approved SA LDs on 20 October 2026. GTA LDs for QLD, NSW and VIC have been published for the 2026-27 season via GTA Member Update No. 17 of 2026, on 28 August 2026.

The industry has agreed to use Bunge and CBH Group published freight rates for South Australia (SA) and Western Australia (WA) each year, subject to approval by the GTA Commerce Committee and the GTA Board.

For non-Bunge sites, (where its main port is a Bunge port) that are linked to the agreed methodology (per SOP) “In SA where a site is not owned by Bunge, the LD shall be calculated using the road distance to port of the particular site based on Google Maps based on the rate/t per km rate for adjacent Bunge sites adjusted for distance.”

NB: WA Location Differentials: Final data for Location Differentials for WA is still to be provided. Once provided and reviewed by the Commerce Committee, given the timing, a decision will be made if Member Consultation will occur prior to Board approval.

3. Location Differentials ARE NOT freight rates

GTA releases Location Differentials each year to enable pricing of the GTA No 2 Contract – Contract for grain and oilseeds in bulk delivered price basing point or port terms (Basis Track) commonly referred to as the “Track Contract”.

The GTA Location Differentials are not published to be a substitute for management of freight price risk and the variation between the LD and the actual cost of execution of freight should be managed by the members commercially.

4. Effective Date

The GTA 2026-27 Location Differentials are effective from 1 October 2026 and are available on the GTA website in PDF form. Location Differentials Look up Database will be uploaded shortly.
