1. Purpose

To advise members that the GTA Board has approved the release of the 2026-27 GTA Location Differentials (LDs) for QLD, NSW and VIC, unchanged from 2025-26, as recommended by the GTA Commerce Committee.

These are available on the GTA website and take effect from 1 October.

2. Background

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

On 2 February 2026, GTA circulated a Member Update, calling for Round 1 Nominations and Submissions. No 2026-27 submissions were received.

As there were no submissions seeking variation, the Board accepted the Commerce Committee recommendation at its meeting on 25 August that east coast LDs remain unchanged.

3. Location Differentials ARE NOT freight rates

GTA releases LDs 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”.

If used for other purposes, users should be aware there may be a difference between GTA LDs and the actual market-related cost of freight execution. This “freight price risk” or “freight basis” must be managed by commercial interests.

Members should regularly adjust their port-based pricing according to their analysis of the LDs and the freight market. GTA LDs are not a substitute for managing freight price risk, and each organisation should commercially manage any variation between the LD and the actual cost of freight execution.

For more information, refer to the GTA Fact Sheet – Understanding Location Differentials.

4. Amendments to LDs in QLD, NSW and VIC

The 2026-27 LDs are unchanged from the 2025-26 LDs.

5. Location Differentials & Amendments for SA and WA

GTA sets the LDs on behalf of industry for GTA member sites only and when requested by a GTA member. GTA generates LDs for QLD, NSW and VIC. In SA and WA, the trade has agreed to use Bunge, CBH Group and other storage operators’ published freight rates each year, subject to approval by the GTA Commerce Committee and GTA Board.

GTA also provides LDs on request for site operators other than Bunge and CBH in these states.

Please note: Until the SA and WA LDs are approved by the GTA Board, the current 2025-26 LDs remain in place.

• SA

The bulk of GTA Location Differentials in SA are derived from the Bunge Export Select Rates provided to GTA.

Bunge Export Select Rates for all their SA sites have not been made available to GTA for 2026-27. They will be available on the GTA website once provided to and reviewed by the GTA Commerce Committee and approved by the GTA Board.

For SA sites linked to a Bunge port where the site is not owned by Bunge, the Committee agreed in 2010 to adopt a methodology based on the net tonnes per km rate for nearby Bunge sites, adjusted for road distance (as referred to by Google Maps) to port and apply that rate.

T-Ports provides a proposed LD for its storage sites to the Commerce Committee for review and endorsement.

SA sites with a port destination in an adjacent state use the same methodology employed in the destination state, eg. VIC.

• WA

GTA anticipates CBH Group and Bunge will provide their 2026-27 rates in October. Following GTA Commerce Committee and GTA Board approval, these will be posted on the GTA website and members will be notified.

6. Effective Date

The GTA 2026-27 LDs are effective from 1 October 2026 and are available on the GTA website.
