Obtained by steam distillation from foliage and terminal branchlets of Melaleuca alternifolia.
Tea tree grows in both New South Wales and Northern Queensland, almost entirely in modern day plantations. Some wild harvesting still occurs but this only contributes a small amount of the 650+ MT that Australia produces annually.
The industry is well regulated and as the original producer of tea tree, Australia standards are highly regarded as the best quality. The harvest period starts in May and lasts until November.
From seed to harvest usually takes around 12-15 months and trees will grow to around 2 metres high. The tree is then cut from just above the ground and the leaves are steam distilled in a process that takes around 1.5-2.0 hours per batch of around 250 kilos. Tea tree will regenerate quickly and over the next 2-3 years will yield higher levels of oil each year and establish a stronger root network ensuring it becomes more resilient to adverse weather conditions. Some more mature trees can yield higher levels of 1,8-cineole, which is undesirable so re-planting can occur every 6-7 years however the tree itself could live over 25 years.

Demand and supply for the oil are low. Harvest operations have been impacted due to unfavourable weather conditions. Floods and persistent rain running into the dry months have delayed harvest operations. This year’s floods have resulted in the loss of 500 hectares of crop. Before the rains, industry estimates predicted production for 2022 to be 1,200 MT. The forecast has now been adjusted to 500 MT. Currently, the oil stock is limited, and the price remains stable.
