Squealing. Not the belts is it? What kind of squeal? Is it worse if you open the throttle hard?
EED - not definitely, but a good indicator. Sometimes broken engine mounts will knock

Any competent mechanic should be able to listen to it and tell you; should be free too. If I were you, I'd pitch up at a few mechanics shops (and remember, bigger is not always better) and ask them.
Come to that, where in Perth are you? I'm probably a bit far away, but if you're willing to travel to Kalamunda I can send you round to Ralph. He's a wrecker with a mechanic's license. Does bloody good work at reasonable rates, much better than Ultra-Tune hehe
