Have you looked at this RichFaces suggestionBox demo yet ? There are links under the examples to view the source.
Edit:
Sounds like you need the value of state in your bean before the user types in the suggestionBox. I would use the RichFaces ajax support to pass the value of state to the bean so when the autocomplete method is called is has the state the user selected on the page to populate a list of suburbs.
