Strata management agreement

Our agreement is coming up for updating. We were presented with an agreement at an AGM and asked to sign. No way.

There were various costs that when asked about, they said that they don’t charge those. Very generous. But on written notification they can charge them if “they want to.”

They had done this with the extra meeting costs.

This seems an unconsolable to be able to raise fees as they like. We don’t have a similar advantage to lower the fees. Is the Trade practices Act relavent to this?
