The correct procedure is for you to make application to your Strata Manager to inspect your Plan's records under Sect 108 of the NSW Strata Schemes Management Act (1996).
The Scheduled Fee is $30 for one hour of “inspecting” pus $15 for every 30 mins after that.
You can take whatever notes you like and/or you can photocopy any pages (although your Strata Manager will probably charge you for the latter), but you can't take any original papers from the file.
