Funding to start a trust

Hi wise ones,
I have a question I hope someone much more intelligent than myself can answer….

I'm seeing my accountant on Friday to extend our non-property related business and have 2 options: (It's for primary production purposes)
1) increase the current Line of Credit/Overdraft (secured by the land) which is in my name by $30,000 for new expenses and have the increase in profit of around $15000 pa added to my personal income tax with the balance paying off the $30000.  I'm on a high tax bracket from my 'real' job. In a few years the $30000 would be paid off and then I could begin to pay down the mortgage on the farm (tax deductable) or invest in more property.

Or

2) Start up another small primary production business in a trust, borrow the $30,000 using the existing land as security and have the profits return to the trust.

In both cases the loans attributed to the farm would increase by $30000 but the aim would be to pay that $30000 back over the next 2 or 3 years so that any extra money made from the new venture after that could be used to invest in property. I could still use the farm as security but also have a very small income stream in the trust of around $15000 which would be in addition to my wage.

My question is this: If I go with the trust option how does the trust repay the $30000 loan that it has secured against the farm? In an offset account linked to the farm it generally takes care of itself, but can the trust make interest free payments to the farm to clear the debt and are these tax deducatble? The idea would be to have the new venture unencumbered within a few years so we can use it as a tool for investing in IPs without tying it to the farm too heavily. Plus, if the trust is positive geared, I believe that's not a bad way to go??

Any other options, comments or advice is welcome
Thanks
