It’s not unheard of that AGMs resolve to remove the ‘10% over budget’ spending limitation for ECs. We do so every year. Better that than have to call an EGM to pay an electricity bill. If your EC acts responsibly & reports back to lot owners every month on how the budget & finances are going you should feel comfortable about how your levies are being spent.
Why don’t you attend a few EC meetings & get a feel for what’s going on, have your say? One person’s frivolous pet project is another’s necessity.
