Australia is quickly becoming a hotbed for innovative companies that blend cutting-edge technology with nature’s intelligence. From harnessing the protein power of cactus leaves to engineering organisms that feed on light, and preserving the traditions of native bush food, these three startups — The Leaf Protein Company, Bondi Bio, and Kakadu Plum Co. — are driving a new wave of sustainable solutions for the planet and its people.
The Leaf Protein Company
Based in Adelaide and founded in 2020, The Leaf Protein Company is on a mission to unlock the world’s most sustainable food source — leaf proteins. At the heart of their innovation is Pereskia, a cactus species that is not only high-yield and drought-tolerant, but also incredibly efficient. Compared to soy, it delivers twice the protein per hectare and uses five times less water than rice crops.
The company’s breakthrough lies in its ability to extract edible protein from the leaves while separating the fiber, which can be repurposed into textiles, animal feed, or even biofuels. This circular approach ensures minimal waste and maximizes resource use, offering a sustainable and scalable alternative to traditional agriculture. The Leaf Protein Company isn’t just making plant protein — they’re building a regenerative food future.
Bondi Bio
Sydney-based Bondi Bio is taking bioengineering to new heights by programming photosynthetic organisms — cyanobacteria — to produce valuable, plant-derived compounds. Since its founding in 2018, the company has been leveraging the natural abilities of these microorganisms to convert light, water, and carbon dioxide into targeted products that serve industries ranging from pharmaceuticals to agriculture.
What makes Bondi Bio truly stand out is its closed-loop production model. Their cyanobacteria don’t require arable land or freshwater; instead, they can thrive in sea, waste, or even polluted water sources. By combining evolutionary biology with modern biotech, Bondi Bio has created a platform that not only mitigates environmental impact but actively contributes to a cleaner planet through carbon fixation and waste remediation.
Kakadu Plum Co.
From Melbourne comes Kakadu Plum Co., a brand that bridges ancient traditions with modern wellness. Since launching in 2015, the company has built its foundation on Australia’s native bush superfoods — most notably the Kakadu Plum, known for its extraordinarily high vitamin C content. But this venture is more than just about health benefits; it’s about storytelling, heritage, and empowerment.
Kakadu Plum Co. works closely with Aboriginal communities to ethically source ingredients, aiming to grow and support the native bush food industry. Every purchase supports traditional landowners and sustains Indigenous knowledge that has been passed down for generations. Through their range of nutritious products, Kakadu Plum Co. offers consumers a chance to nourish both body and culture.
