The system is designed to handle location addresses in a structured manner, ie one or more address lines, a suburb, a postcode, and a state. Note however that you do not explicitly set the country - although this is implicit in the state (since each is associated with a country).

If you have to hold addresses in different countries, there are two possible approaches:

1. put the whole address in the address lines, and leave the suburb, postcode, and state fields empty
2. create the states and suburbs for each 'foreign' country

The second approach will potentially result in a long list of states (since it will include those from all countries). Hence the best approach is probably the first.
