Indonesia, a beautiful Southeast Asian nation made up of thousands of volcanic islands, is home to hundreds of ethnic groups speaking many different language. Indonesian rich history has been influenced by foreign powers drawn to its natural resources. With an abundant of green forests on all of its islands and half way between the poles, Indonesia was nicknamed ''The Emerald of the Equator''. It is famed for its beaches, volcanoes and jungles sheltering elephants, tigers and Komodo dragons.

Perth is the capital and largest city of the Australian state of Western Australia. It is the fourth-most populous city in Australia, with an estimated population of 2.02 million (as of 30 June 2014) living in Greater Perth. Perth is part of the South West Land Division of Western Australia, with the majority of the metropolitan area of Perth located on the Swan Coastal Plain, a narrow strip between the Indian Ocean and the Darling Scarp, a low coastal escarpment. The first areas settled were on the Swan River, with the city's central business district and port (Fremantle) both located on its shores. Founded in 1829 as the administrative centre of the Swan River Colony, Perth became known worldwide as the "City of Light" when city residents lit their house lights and streetlights as American astronaut John Glenn passed overhead while orbiting the earth on Friendship 7 in 1962.

Semarang is a city on the north coast of the island of Java, Indonesia. It is the capital of the province of Central Java. A major port during the Dutch colonial era, and still an important port today, the city has a dominant Javanese population. Semarang is a bustling mid-sized city with a population of 1.5 million. More a business than tourism destination, it nevertheless has its own charm with contrasting modern mid-rises, Dutch colonial architecture, Chinatown, and small "kampong" jutting against each other.

Surabaya is Indonesia's second-largest city with a population of over 2.7 million, and the capital of the province of East Java. It is located on the northern shore of eastern Java at the mouth of the Mas River and along the edge of the Madura Strait. To Indonesians, it is known as "the city of heroes" due to the importance of the Battle of Surabaya in galvanising Indonesian and international support for Indonesian independence during the Indonesian National Revolution. The city's tree-lined streets, street parks and renovated pavements will impress those newly arrived from other cities in the archipelago, though in general the city's attractions tend to be more apparent to those who make it their home rather than to short-term visitors.
