tax issue - is interest deductible?

Hi,

I have a tax question regarding tax deductible interest.

I am aware that interest incurrred on a margin loan for shares is tax deductible, however the portfolio of shares I want to invest in are small to mid cap growth stocks, the majority of which are not available to margin lend via the financial institutions I have looked into.

To get around this barrier I was planning on getting a personal loan to purchase this portfolio of shares, however would the interest rate be tax deductible?

If so is there a specific product that a financial institution offers in this scenario, like an investment loan or can I just get a normal personal loan?

If not, is this because for interest to qualify to be deductible a particular share has to have a dividend scheme and therefore is seen as an income producing investment in the eyes of the ATO?
