Usually not for straightforward tribunal matters — they're designed for self-representation. You should consider a strata lawyer for complex cases (defects, large damages claims, manager removal contests) or where you're going against a represented party.
Specialist strata lawyers usually charge $400–$700/hour but a 1–2 hour scoping session is often all you need to map out a strategy and draft your application. The owners corporation can fund legal advice from the administrative fund subject to budget approval.
