I think Flame Tree is trying to say:
1. There used to be an automated system for watering the garden. It stopped working after some tiling work was done. No effort taken to repair / replace the watering system.
2. Until recently, a gardener was employed to water the garden. Now this gardener is no longer watering the garden.
3. Committee is now looking for an owner to water the garden and be paid for it.
4. Flame Tree wants to know:
(a) What kind of discussions were held by the Committee to take this course of action?
(b) Is the cost of paying an owner is in the budget or approved in an AGM?
You should ask your strata manager or Committee. I can’t speak for Qld but it seems reasonable that owners receive the minutes of all meetings held. Owners should also have seen a proposed budget and then approved it a general meeting.
If your strata manager is not distributing meeting notices with proposed budgets, they are not doing their job. If the owners don’t read the meeting notices, they are not doing their job either.
