Kai Kai Farm is a family-owned mushroom farm located at Tamborine Mountain. It began by growing organic, no-spray gourmet mushrooms for local chefs and has evolved to offer a complete range for the modern grower. The farm specialises in gourmet and functional mushrooms, mushroom kits, cultivation supplies, Bokashi bran, and fermented plant extracts.

They provide fresh gourmet mushrooms such as Lion's Mane, Gourmet Mushroom Medley, Oyster Mushroom Medley, and Organic Shiitake. Their mushroom kits include Lion's Mane 'Pom Pom', Pink Oyster, Pearl Oyster, and Yellow Oyster varieties. The farm emphasises sustainable, organic, and spray-free practices, using the same professional-grade supplies they offer to customers. They also provide earth-friendly home and garden solutions including Bokashi composting and fermented plant extracts.

The farm operates an online shop with delivery available, offering free shipping on all mushroom kits. They provide guides and FAQs for their products to support customers.
