Apathy – what to do about it?

Newbie to the forum, but i thought this was the most appropriate place to post.

I am trying to help out some pensioner couple living in a small block of 10; They are residents, and seem to be the only one who “cares” about their block / living environment. They are the only ones who turn up to AGM’s year in / year out. Other owners could not care less due to any of a) apathy b) don’t understand how a schema operates, think the Strata Agent is GOD c) are landlords not living there, as long as the rent is collected d) lower-socio economic status / english not first language e) other reasons.

So the Managing Agent knows this, and does a minimal job just to thick all regulatory boxes, but no real action on the ground; ignores requests for this and that, raises special levies for X, but does not follow through with actioning X, etc

Given the owners don’t talk to each other / are not on site / think they are powerless to do anything about it – Can my pensioner couple friends do anything that would lead to replacing the Strata Agent?
