Honouring Indigenous Knowledge: More Than Ingredients
Aboriginal and Torres Strait Islander peoples are the original custodians of the Australian landscape and its extraordinary biodiversity. For over 60,000 years, they have cultivated sophisticated, land-based knowledge systems—deeply connected to Country—that include the use of native plants for healing, nourishment, and cultural practices. This ancestral wisdom forms the foundation of many modern skincare ingredients, with plants like Kakadu Plum, traditionally valued as an antiseptic and immune booster, and Tea Tree, used on wounds and for respiratory relief, playing vital roles in bush medicine for generations. Quandong kernels provided nourishing oils for skin and hair, while Pepperberry leaves and berries were applied to soothe sore muscles and calm inflammation. Even Emu Bush was infused for antimicrobial washes to treat skin injuries.
Today, modern science is only beginning to catch up with this deep intergenerational knowledge. Studies confirm the antioxidant, antimicrobial, and anti-inflammatory properties of many traditionally used botanicals, validating their long-standing use in caring for the skin and body. As these ingredients gain global recognition, ethical brands are increasingly partnering with Indigenous communities to ensure fair benefit-sharing, respect for cultural heritage, and the preservation of traditional custodianship of Country, supporting both biodiversity and cultural continuity.
Respectful Collaboration and Ethical Sourcing
Today, a growing number of skincare brands are acknowledging the importance of not only using native ingredients but also working in partnership with Indigenous communities who have nurtured and protected these resources. This includes:
- Engaging in benefit-sharing agreements aligned with the Nagoya Protocol and Australian Indigenous Knowledge frameworks
- Ensuring that harvesting practices are led by or in consultation with Traditional Owners, supporting Indigenous enterprise and community autonomy
- Avoiding cultural appropriation by respecting the sacred or ceremonial use of particular botanicals
When brands source ingredients like Kakadu Plum or Pepperberry through Indigenous-owned operations or ethical supply chains, they are contributing to cultural preservation, economic empowerment, and ecological stewardship.
More Than a Trend—A Living Knowledge System
These aren’t just “superfoods” or skincare trends. They are part of a living, ongoing tradition of care for people and Country. Whether it’s the use of crushed tea tree leaves on wounds, the oil from quandong kernels to moisturise skin, or the application of wild-harvested emu bush as an antimicrobial wash, each remedy holds significance beyond its topical effect.
By choosing products that celebrate and respect this wisdom, consumers help ensure that the benefits of Australia’s native botanicals are shared fairly, sustainably, and with the deep cultural integrity they deserve.
Australia’s Skincare Exports: Natural Ingredients on the Global Stage
Australia has become a global supplier of unique natural ingredients prized in clean and sustainable beauty. From nutrient-rich botanicals to mineral clays, these exports are shaping skincare routines worldwide while raising important conversations about sustainability.
🌿 Tea Tree Oil leads the pack, with Australia producing over 80% of the world’s supply. Grown on plantations mainly in New South Wales, it’s exported globally for its antibacterial and anti-inflammatory properties, making it a staple in acne treatments and natural cleansers.
🌿 Kakadu Plum is another star export, highly sought after in Asia and Europe for its exceptional vitamin C content and antioxidant benefits. Wild-harvested predominantly in Northern Australia, ethical sourcing programs work closely with Indigenous communities to support traditional custodianship and ensure sustainability.
🌿 Sandalwood (Santalum spicatum and plantation-grown S. album) continues to be a major export, used in skincare and perfumery. While wild Australian sandalwood has suffered from decades of overharvesting, plantation-grown Indian sandalwood now provides a more sustainable alternative.
🌿 Macadamia Oil and Lemon Myrtle Oil are also rising stars. Both are cultivated sustainably and exported for their nourishing and aromatic qualities in creams, serums, and natural fragrances.
🌸 Australian Pink Clay, celebrated globally for its gentle detoxifying properties, has gained immense popularity in masks and scrubs. However, increased demand has led to overmining concerns. Extracting kaolinite-based clays involves open-pit mining, which can disrupt ecosystems and cause land degradation if not carefully managed. As a result, ethical sourcing and site rehabilitation are critical to ensuring the long-term viability of clay exports.
As these ingredients reach global markets, they showcase the richness of Australia’s biodiversity and Indigenous knowledge systems. But they also highlight the need for careful management of natural resources—balancing global demand with local environmental and cultural responsibilities.
