As nobody’s jumped in (yet), here are my comments.
The Strata Managing Agent is working for YOU, so unless they’re complicit in some way in the underhanded activities that I recall you mentioning in an earlier post, there’s absolutely no reason for them to hold back any of the records that they’re holding on YOUR behalf.
That said, it would be fair and reasonable for you to contact your Strata Manager in advance to give them a heads-up concerning precisely what records you’re intetested in. You might consider taking another Owner with you; many hands make light(er) work!
In general terms, your Strata Manager will be holding all your Plan’s financial records, income and expenditure statements, copies of all incoming and outgoing correspondence, copies of any Notices-to-Comply (with By-Laws), and the Agendas and Minutes of General Meetings and of Executive Committee Meetings.
If by chance you experience road-blocks with regard to cooperation by your Strata Managing Agent, then (if you haven’t done so on this occasion) you should seek a further Meeting in writing and under the provisions of S108 of the NSW Strata Schemes Management Act where, as you will be required to make a small payment ($30 for the first hour), you can reasonably expect your Strata Manager to do something in return – like assist you to locate the records that you seek.
