It's hard to know what your options are without seeing your contract (especially since this guy is clearly not a straight-shooter). My advice would be to immediately contact a reputable strata management firm, definitely a member of Strata Community Australia, their professional body, and tell them that if they help you to remove this guy, they can have the contract. Take the strata management contract with you. In the meantime, pass a motion at your next EC meeting – oe even agree by email or phone – to let this guys know that he will have to reapply to continue his contract after it has lapsed. There wioll be a clause in the contract telling you how much notic you need to giver him. However, there may alsoo be clauses related to failure to perform his duties, in which case you need to pass a motion telling him this is the case and that his services are no longer required. By the way, this is all a lot easier if you have another Strata Manager ready to pick up where this guy left off.
