How to access a property list

I have created a property list with continents, countries, and random facts as shown below:

I can access the top level keys from the property list easily enough:

if let path = NSBundle.mainBundle().pathForResource("countryData", ofType: "plist") {
            dict = NSDictionary(contentsOfFile: path)
        }
countries += dict!.allKeys as! [String]

If I wanted to access the second element in the vanuatu array, however, things fall apart. I would think objectForKey would get the country dictionary and then use objectForKey again to get the country array. But so far, that hasn't worked. At all...

if let path = NSBundle.mainBundle().pathForResource("countryData", ofType: "plist") {
            dict = NSDictionary(contentsOfFile: path)

            if let australia = dict["australia"] as? [String:AnyObject]{
                // access the second element's property here
            if let vanuatu = australia["vanuatu"] as? [String]{
                // Access the vanuatu here
                } 
            }
        }
