Members of the Committee can be paid, but only if that’s resolved by those present at a General Meeting of the Owners Corporation (O/C), and then only for their role on the Committee with payment being made twelve (12) months in arrears; that is for services provided not for those to be provided.
So the work that your Secretary’s paying herself for does not meet the requirements of NSW Strata Schemes Management Act with regard to Committee Members being paid, and unless she’s been engaged by the O/C, is covered by indemnity insurance, has an ABN, and properly invoices the O/C then she’s also in breach of audit provisions and her activities must cease.
That can be resolved by a majority vote of the Executive Committee, the O/C, or by the Strata Manager if they’re making the payments (which will likely breach their own internal procedures and those in the NSW Property, Stock, and Business Agents Act).
