Hi KB
According to the fair tradings' strata living brochure (https://www.fairtrading.nsw.gov.au/pdfs/About_us/Publications/ft045.pdf) which is the only thing I can find on the issue, “a person is not classified as a ‘caretaker’ if they carry out the duties of a caretaker on a voluntary or casual basis or as a member of the executive committee.”
So by definition, they cannot be both caretaker and EC member…however, the caretaker agreement must be clearly defined and this should be available on request.
