1. Purpose

To advise members, the GTA Board has approved for release the 2025/26 GTA Location Differential (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 2025.

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, GTA Board approved SA LDs on 30 September 2025. GTA LDs for QLD, NSW and VIC have been published for the 2025/26 season via GTA Member Update 15 of 25, on 29 August 2025.

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: Final data for Location Differentials for WA is still to be provided. Once provided and reviewed by the Commerce Committee, it shall decide if a Member Consultation process is warranted.

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 2025/26 Location Differentials are effective from 1 October 2025.

5. Excel Format

The GTA 2025/26 Location Differentials are available for GTA Members in Excel format.
Please send your request for these to admin@graintrade.org.au and include “Excel Location Differentials Required” in the subject field.
