[1] The appellants in each appeal, Appeal No 5587 of 2004 (Mr Borg) and Appeal No 5496 of 2004 (Messrs Coppo, Gottke, Sich, Cameron, Rapson and Jozinovic) were employees in the central Queensland mining industry. In 1999, they became involved in a tax minimisation scheme that is central to these appeals. Banalasta Oil Plantation Ltd ("Banalasta"), a respondent to both appeals, was established to make a profit from the production and sale of eucalyptus oil and associated products. Mr Horner, the salesman of the scheme,[1] was employed by the accounting firm, SecureInvest Accounting Services, whose partners were Mr Pawski and Mr Nunis ("the accountants").[2] The scheme worked in this way. The appellants entered into the Banalasta Natural Oil Joint Venture Project No 1. The joint venture agreement was for ten years. The scheme's prospectus anticipated that from 30 June 2001 participants would be making a profit on their Participation Interests;[3] participants were obliged to pay significant prescribed annual fees.[4] The financier, Plantation Equity Pty Ltd ("Plantation Equity"), a company associated with Banalasta[5] and a respondent to both appeals, advanced money to each appellant by way of a loan; Plantation Equity then paid the loan amount advanced to each appellant, less the accountants' fee, to Banalasta. In return each appellant acquired a capital investment and Participation Interests in the joint venture.[6] This prepaid expenditure was said to further primary and secondary industrial development and to be claimable as a tax deduction. Each appellant then claimed as a tax deduction the money lent to them by Plantation Equity, greatly reducing their annual assessable income. They used the resulting tax refunds as their first instalment to repay the loan to Plantation Equity.
