it isn't recommended to have a self managed super fund unless you're earning $300k+ a year. Otherwise you pay too much in fees.
I think you are meaning to say that the balance of the fund should be $300K or more. I think $200K or more is more realistic if you are planning to add to it (as in over & above the 9%). For the vast majority of people in the age group of the majority of BBer's, a SMSF wouldn't be worth it due to having a low balance and not adding extra to it as needing money for everyday living/mortgage etc. There's also a lot of rules and restrictions.

As for the original question, I would check the websites of some of the more popular ones & compare fees & historical returns. A financial planner could help also but I would be wary. Many receive a commission for placing you in a fund and a trailing commission for however long you stay in that fund. Bank based financial planners will generally only recommend their own bank's products or those of companies that are owned by that bank. A financial planner that charges a fee for service rather than a commission will not have the same conflict of interest but they are hard to find :/
