The Wombat File Is Yours to Keep

So sorry to be so late with these clues to round three's questions. It's a long story and to tell it would be to extend the delay.

Due to the appalling delay, you have until Friday morning (January 5th) at 10 A.M. E.S.T. to submit final answers.

Without further ado:

1. The main answer for this question is very close to No. 5.

2. This country is not currently part of the European Union.

3. The smallest of these is only 26 square kilometers, has few natural resources, and has attempted to supplement the national income through a particular facet of the Internet economy. The two largest are landlocked nations.

4. The continent in question is not Africa.

5. The state in question is the 8th most populous in the U.S. and has more lighthouses than any other state.

6. One of the two countries that share jurisdiction over this territory is a rare "doubly landlocked" nation -- that is, landlocked itself, it is also surrounded by landlocked countries. The other country in question is the 9th-largest by area in the world. The fact that "Renaissance Island" is no longer an island is the direct result of human activity.
