If you're under age 55 and in good health generally you cannot withdraw your funds from super and your super fund cannot provide you with any financial assistance eg lend you money. However, for a very small percentage of people with unrestricted non preserved superannuation components ( check your statement most people's superannuation is 'preserved'which means they cannot access it until they meet a 'condition of release')they may withdraw their super benefits upto the unrestricted non preserved amount.
For healthy (& able) persons aged 55 and over they may access their super under the following conditions:
- As a pension whilst still working
- as a pension or lump sum if they permanently retire, change employment from age 60 or attaining age 65( regardless of your employment)
I can understand your frustration of having your money compulsory tied up in superannuation especially given the poor investment returns of the past 5 years. However, superannuation may be more flexible than you realize, I am an adviser at Grant Thornton and I am constantly telling clients that superannuation is not an invest but it the most tax effective long term savings vehicle available to Australians for their investment savings eg max 15% tax on income and capital gains if held for a year are taxed at 10%.
If you're not happy with your investment returns you may like to seek some advice or,set up your own super fund - a self managed super fund where you can invest a wide variety of assets; shares, managed funds,cash, term deposits, property( your super fund can even borrow to help acquire the property)
I hope this helps
