This from Fair Trading:
For the purposes of the Act, a person who acts as a … strata managing agent must hold a strata managing agent’s licence.
A strata managing agent is a person (whether or not such person carries on any other business) who, for reward (whether monetary or otherwise), exercises any function of an owners corporation within the meaning of the Strata Schemes Management Act 1996 or any other function that is prescribed by the regulations under the Act.
The key to whether or not they need a license is whether or not they get financial or other rewards. That means a member of the EC can fulfill the functions of a strata manager provided they don't take any reward or payment for it
