Central America to Miami
 

can anyone tell me options to get me and bike from Central America (I'm thinking Belize) across to Miami (maybe via Cuba?). trying to plan a trip next year from South America to Central but need to get bike back to Australia at end and I'm thinking from the states would be easier for that. If this is feasible I can book some return tickets. Also any advice/contacts in freighting back to Australia from Miami would be great.
cheers
