Strata Managers will often tell you that smaller complexes are much less cost-effective for them to manage because the basics take just as mush of their time but there is a smaller pool of volunteers from which to draw EC members to run the building, creating issues. Also, in smaller complexes, the issues can get very personal very quickly which creates a lot of telephone and email traffic. However, there is a limit on how much they can charge in a competitive market.
Strata Community Australia are not allowed to set fees for their members as that would be considered anti-competition. As afar as fees for photocopying are concerned, this is something you should negotiate in your contracts. However, you will get good advice from the Owners Corporation Network (www.ocn.org.au) on what others pay.
