Hi,
If your a current financial member of the strata scheme you are entitled to be advised of any matters which effects the common ground of the property in joint.
The strata manager agent should ownly act on the lawful direction from your EC or advise on state reg’s.
Your EC has limited power to act alone on expenditure with out the majority vote.
Regardless of the invasion of privacy quote from other body corp member, you can vote them out and change the agent if the majority consider it to be in there best interest.
Kind Regards.
