Two comments here for jlong and daphne…..
1) I earlier today posted the name of company called Strata Match whose ad I heard on a Sydney radio station yesterday. I know absolutely nothing about this company, but they appear to provide a service that’s similar to those companies who match / compare private health insurance providers. They list a phone contact on their website, so maybe give them a call in the first instance to see if they provide the type of service that you’re looking for.
2) Careful about changing strata managers without first reading the termination clause of your Plan’s Agreement with its current provider. As Kiwipaul said you’ll need to resolve to do that at a General Meeting, and that may need to be convened at least 3 months before the desired termination date, as most Agreements require that period of notice to terminate without penalty.
