The NSW government used to publish a very useful guide to living in strata (called “Strata Living”), but they have discontinued that, for some bizarre reason – but it’s available on some other sites, although it is now a bit out of date, so google that document. Here is a source => https://nsw.strata.community/wp-content/uploads/2014/06/Strata_Living_Guide-2018.pdf
That guide gives you a good introduction for how to live in a strata building, and how to be part of a strata committee.
