Understanding the Company Secretary's Role
When registering a new company with ASIC, the role of company secretary is considered an ‘officer’ of the company and has a lot of the same duties and obligations to an organisation that directors have. Modern company secretaries provide advice to the company and promote and instruct good governance practices.
Registering a secretary is not legally required for a PTY LTD company although some people choose to. If selected, the secretary will have to co-sign documents (unless is a BOTH director/secretary, then only sign as director).
