Unfortunately there is no requirement (in NSW) at least that you be sent a copy of Exec Committee Minutes, putting them up on a noticeboard will suffice.
Have you requested that the Managing Agent email you a copy – he/she doesn’t have to but may be willing to do so.
You are entitled to look at the records of an Owners Corporation at the Managing Agent’s premises, and copy those records, on payment of a fee. You could authorise someone else to do that for you.
I’d suggest that you keep an eye on your property whenever you can get the opportunity. If you need to travel to do so, reasonable costs involved in inspecting your property should be a tax deductible expense.
