Currently any variation on AOC
If the ACN is the same and there are no changes in Directors, staff, etc., a change of company name has nothing to do with the operation of an AOC.
A two line change to the OM (for Blogs read Smith) and a new Compliance Statement would all that is required.
I would like to see references to any Regulations that requires anything else.
By sticking ya head up, it could awake CASA and trigger an audit if one has not been done within the normal cycle.
