lukehadji,

There are two kinds of options. One kind is traded like shares are traded and have O, OA, OB, OC, etc., after the company code, e.g. BODO, BODOA, BODOB.

The other kind of option is a contract and is NOT traded in the same way as shares. The ASX website has good basic educational materials on these. Here's an online course:
