Abstract

Australian tea tree (Melaleuca alternifolia) is a woody plant that produces an essential oil with antiseptic, anti-bacterial, anti-fungal, and antiinflammatory properties and is widely formulated into many products. Yield and financial analyses were done to compare the viability of replanting 20 ha tea tree plantations using elite clones and improved seedlings over a 15 year time frame were carried out. Four plantation options were modelled: (1) plantations established using genetically improved seedlings (ATTIA 2B) planted at a stocking of 33,333 plants/ha and (2) 16,667 plants/ha, (3) plantations established using the best three selected clones planted at a stocking of 33,333 plants/ha and (4) 16,667 plants/ha. Financial analysis showed that, at an oil price of $45/kg (as at Sep 2008), replacement plantations of either elite clones or improved seedlings are both highly profitable irrespective of the stocking employed. The Net Present Values per hectare at 7% discount rate was $107,824, $63,640, $163,162 and $104,055 for plantation options 1, 2, 3 and 4, respectively. Plantation option 3 was predicted to give the greatest profit at any of the oil prices tested, followed by plantation option 1, 4 and 2. The breakeven prices for tea tree oil production, using the production parameters in this model were $11.81/kg, $15.19/kg, $10.72/kg and $12.96/kg for plantation options 1, 2, 3 and 4 respectively.
