Who Are GSSW

GSSW are a family owned and operated business. Having been involved in broadacre farming for over 30 years they understand how important it is for your operation to have the highest quality seed.

Without clean seed you’re putting yourself at a disadvantage from the get go. By starting the season with a full and vigorous seed, you are able to achieve a much higher yield than would have otherwise been possible.

At Great Southern Seed Works it is their mission to provide the best grain cleaning service available to farmers and growers in the Great Southern Region and Surrounds.

Why do we do what we do? Well… we just love it.

We enjoy being able to solve a problem for our clients and giving them the confidence to trust us with their product.
