You definitely can't just take it out. There is a provision for financial hardship that requires you to have been on CL for a certain length of time (6 months I think but not 100% sure). That might be what you are thinking of. It can be difficult to get but you may be eligible depending on your situation. I think there is a limit of $10K (again not 100% sure).

You can shop around for another fund with lower fees, or look to change your underlying investment strategy. I think the default for most funds is "balanced" but you can go a more high risk option with the potential for higher gain or higher losses depending on what happens or a cash strategy which is similar to a high interest bank account but still through super. All options will have fees. Some funds are higher than others. Theoretically, the investment returns should more than cover the fees but the sharemarkets haven't been performing well for the last few years so most have lost capital.
