About Us

Mushroom Farmers for 3 Generations

SjW Mushrooms was started by Steven & Joanne Willemse in 2011, 

Having worked across all areas of mushroom cultivation for over 35 years, Steven has a reputation as being one of the best mushroom growers in Australia. 

Today, the SjW Mushrooms farms at Chevallum employ over 20 staff and produce 8 tonnes of mushrooms a week.

Twenty percent of the SjW farm's product goes to Brisbane and surrounds, as wholesale outlets throughout Queensland.


SjW also supply local Sunshine Coast businesses, leading restaurants, and Independent Supermarkets.

“I go and buy my mushrooms from here regularly. The staff are so friendly and helpful & the mushrooms are devine. Makes a huge difference to your meal when your mushrooms are so fresh. We have also got some compost from here and it was the best for our garden. If you haven't been here yet you are missing out”.
