No super fund is secure unless you run it yourself. SIMPLE.
Even if you run it yourself its still a waste of your money and time.
Superannuation is a scam top down and if you are asking this question you have already been conned. It was designed to make a thriving stock market, run by inexperienced graduates who care nothing about your money but lots about their Friday lunch.
Take your super out and run your own fund, a half decent accountant can set it up for less than a grand. Super funds can lend to business at 13.5 %. Thats a good return and businesses will jump at that.
Take charge of your own money my friend. Don't leave it to middle management buffoons.
