About us

Hexcyl Systems Pty Ltd was founded in 2007 by four Australian Oyster Farmers with over 60 years collective experience using ADJUSTABLE LONGLINE SHELLFISH FARMING in South Australia and Tasmania.

Our Roots in Oyster Farming

Our Roots in Oyster Farming

Founded in 1988 by Garry Seidl, his brother Andre, and sister-in-law Wendy, West-Eyre Shellfish has grown from a 10-hectare site near Ceduna to 40 hectares in Denial Bay and the Nuyts Archipelago, producing Pacific Oysters for domestic, export, and on-grown stock markets. Frustrated by the high cost and environmental impact of broken oyster baskets, the family designed the Hexcyl Oyster Basket, creating a robust, durable solution that delivers up to 40% more productivity, improved stock quality, and reduced operating costs, cementing their reputation as innovators and pioneers in South Australian oyster farming.

Driven by a desire to improve productivity and durability, the Seidl family assembled a committed team of industrial designers, tool makers and moulders culminating in the design and manufacture of the world leading Hexcyl shellfish basket design.

Hexcyl transformed oyster farming by providing a stronger, longer-lasting, and environmentally responsible solution that farmers can rely on.

Team & Expertise

Garry Seidl

Garry is a qualified Fitter and Turner by trade which has enabled him to utilise his skills to pursue design and implementation of new and improved oyster farming methods and infrastructure. The dissatisfaction of the performance and longevity of then existing infrastructure was the reason leading to the establishment of Hexcyl Systems Pty Ltd in 2006 with two other key shareholder businesses.

Garry is heavily involved in product design and testing of all infrastructure components ensuring the products design is fit for purpose in the harsh marine environs where oyster farms are situated. As Managing Director Garry oversees both the product design and development as well as direction and growth of the company with the support of Company Directors.
