Our Process

The most extensive, single Tea Tree plantation in the world, coupled with a central high-efficiency distillation facility. Including complementary storage and packaging.

From our nurseries to our fields, every plant receives the same level of expertise and dedication, producing the highest quality oil ever. Our entire process is certified with an ISO9001 Quality Assurance System certification.


Main Camp Natural Extracts Pty Ltd currently has 2000Ha of Tea Tree plantations, ranging from the Far North Coast of NSW to the mid-North Coast of NSW. Half of these were planted over 20 years ago. The remainder has been established with the growing demand over the last 5 years.

Two large dams provide the plantation with excellent water security. The trees are harvested once annually. Fertilizing regimes and the integrated pest management system represents the industry’s best practices and ensures that pure, clean and consistent biomass can continue to be fed into the distillery. Much of the ISO14001 accredited Environmental Management System is associated with the farming practices and our commitment to sustainability.


Harvest day at MCNE is when the magic continues to happen. It’s when the beautifully cared-for tea tree plants are harvested to create one of the world’s most purest Tea Tree oils. Watch the video to see harvest day in action.


The Main Camp distillation plant was made according to GMP (Good Manufacturing Practice) standard. Implicit in the design, philosophy was operator functionality and safety, low maintenance requirements and a readily expandable configuration. The Main Camp steam distillation technology is the most efficient in the industry arising from over 20 years of development and process refinement. Main Camp maintains a continuous improvement programme that will provide further efficiencies.

The plant operates on a batch basis using up to 4 reactors at any one time. Steam is provided by a high-efficiency dual fuel fired boiler. The distillation plant has substantial capacity over the current plantation output. Although the process uses relatively large quantities of water, all of the process water is recycled. More then 98% of the Tea Tree biomass processed is subsequently returned as soil and garden mulch.


Multiple stainless steel storage tanks support proven storage, transfer and packaging procedures that softens the oil odour and avoids oxidative deterioration of the oil.

The finest quality oil is consistently produced using procedures throughout the entire process that are all accredited with an ISO9001 Quality Assurance System certification which ensures full traceability.
