Can I Borrow From Family To Invest In Shares?

In Australia, I was wanting to borrow $100k from family at say 10% p.a. to buy shares (like you would a margin loan). This would generate $10,000 a year in interest payable to the person I borrowed the money from. Am I able to deduct the $10,000 interest from my taxable income as is the case with a bank offered margin loan or can I not deduct this $10,000 from my taxable income as it's not from a bank? Thanks!
