Control is available as a method of perfection for only six (6) classes of collateral, mainly financial collateral, being:

1. ADI accounts (bank accounts);
2. intermediated securities (for example, ASX-listed shares);
3. investment instruments (for example, unlisted shares, bonds and units in managed investment schemes);
4. letters of credit;
5. negotiable instruments not evidenced by a certificate; and
6. satellites and space objects.

There is discussion on perfection by control over these classes of collateral at paragraphs 17.6.1 to 17.6.30 of Chapter 17 (Perfection).
