Caretakers are non-voting members of the committee.  Given their role, caretakers almost always provide a report to each committee meeting.  The report should include significant events, unusual items they have attended to and requests for future spending and/or projects.  Use your liaison person to request the caretaker tailor the report to your needs.  Also understand that the reports will be a body corporate record and therefore available to all owners and other interested persons on a search.
