Your Owners Corporation (i.e. the 12 Owners) has entered into a Strata Management Agency Agreement (SMAG) with its Strata Manager, that in addition to it’s legal framework sets out what services will be provided and at what cost.
You need to obtain that SMAG from your Strata Manager or from the Secretary of your Executive Committee, who should have been provided with a copy at the time of signing, and have a very thorough read through the document.
There will be a number of attached Schedules, and to answer your question you’re looking for one titled something similar to “additional charges” or perhaps “associated fees” where as that title implies, there will be a number of listed services and their associated fees. Sorry for the vagaries, but our Plan’s self-managed and I haven’t see a SMAG for almost 10 years.
The two (2) fees to which your post relates appear (logically) to be for your Plan’s use of some strata management software for which your Strata Manager’s purchased a License, and for their fee to keep and report upon your Owners Corporation’s Trust Accounts (the Admin and Sinking Funds) in accordance with the provisions of the NSW Property, Stock and Business Agents Act (2002).
Whether those fees can be justified is a whole other question, but if they’re not listed in one of the Schedules to the SMAG then you have a case to have your Strata Manager reverse them, and if they are listed, then like a lot of other Owners Corporations yours will have to live with it until the date that the SMAG may be reviewed; that date too will be shown within the document.
