The AMGA works with all parts of the supply chain, from production through to the consumer. By working together, we seek to continually improve our growers’ ability to provide a healthy, profitable and safe product for all consumers. As part of this continual improvement, we work with Hort Innovation to ensure the industry levy funded Research and Development and Marketing programs for the Australian Mushroom industry are well directed and responsive to industry needs.

The AMGA’s Governance:

The Australian Mushroom Growers Association is governed by a Board of Directors responsible for setting the strategic direction of the organisation. The Board comprises elected grower and industry members and AMGA members can stand for election to the Board at the AMGA AGM.  The AMGA office’s role is to manage the organisation’s business and implement the Board’s directions.

The AMGA's History:

The origin of commercial mushroom growing in Australia can be traced back to 1933 in disused railway tunnels under Sydney – including the incomplete Circular Quay to St James line. In the late 1930’s the mushroom industry moved outdoors to the Hawkesbury district when growers created the first raised beds in open fields, covered by nothing more than straw and hessian bags. It was hard going, with low yields and fragile mushroom crops at the mercy of Australia’s weather extremes. Relying on the expertise and hard work of newly-arrived migrants, the Australian mushroom industry became a reality.

With growing techniques in the 1940s and 50s still largely unchanged from the methods used in 19th Century Europe, mushrooms were very much a seasonal crop in Australia, produced during the cooler months.

It wasn’t until the 1960s that modern mushroom farming emerge on a world-wide basis. In 196, 18 growers attended a meeting in Parramatta to discuss the future of the mushroom industry.

From these humble beginnings, the Australian Mushroom Growers Association (AMGA) was formed. Committed to mushroom growers and the mushroom industry, the mission of the AMGA is simple: to provide wholesome food for the community.

In 2021, Australian Mushroom Growers celebrated 60 years of growing together.

The AMGA’s Board of Directors and Governance:

The Australian Mushroom Growers Association is governed by a Board of Directors responsible for setting the strategic direction of the organisation. The Board comprises elected grower and industry members and AMGA members, who can stand for election to the Board at the AMGA annual general meeting.

The following directors form the elected Board of Directors of the Australian Mushroom Growers Association for 2021/22.
