More than half the strata schemes in NSW are self-managed. Just arm yourselves with the available literature and find out what your obligations are regarding meetings etc.
The Strata Community Australia free online course for strata committees is offline at the moment while they bring it up to speed with the new strata laws that came in last year. But it should be back soon.
This page on this website has links to lots of valuable information, including the Strata Act and Regulations and there’s plenty of other information you can use.
