I think the best way to deal with this may be to force the other owners to get involved by invoking section 232.1 (e) and 232.2 (below) which is to seek Tribunal orders compelling an owners corporation to fulfil its duties to all residents.
So what you could do is list all the issues that are demonstrably breaches of by-laws or of the Act and ask the Owners Corp or strata committee to issue Notices To Comply.
If they refuse fail to do so withing two months, you can then take them to the Tribunal who should order them to do so.
Obviously, there will be a backlash from your neighbour of some sort, but at least it will be the Owners Corp who are issuing the complaints and not you personally.
(1) Orders relating to complaints and disputes
The Tribunal may, on application by an interested person, original owner or building manager, make an order to settle a complaint or dispute about any of the following:
(e) an exercise of, or failure to exercise, a function conferred or imposed by or under this Act or the by-laws of a strata scheme,
(2) Failure to exercise a function
For the purposes of this section, an owners corporation, strata committee or building management committee is taken not to have exercised a function if:
(a) it decides not to exercise the function, or
(b) application is made to it to exercise the function and it fails for 2 months after the making of the application to exercise the function in accordance with the application or to inform the applicant that it has decided not to exercise the function in accordance with the application.
