Funny you should say that, this morning I’m meeting someone from a company called Stratamatch a kind of dating agency for strata plans and SMs. Look them up on stratamatch.com.au and let me know how you go.
Meanwhile, this is always the danger when you give your SM the obligatory three months notice that you are sacking them. I would always follow that up with a notice that you are putting the job up for tenders and inviting them to re-apply.
Your current SM shouldn’t leave you high and dry but somebody better gets their hands on the chequebook soon or you are going to have unpaid bills and a whole mess of other problems.
