There are four administrative districts that comprise the Sultanate of Brunei. It is situated in Southeast Asia, close to Malaysia and the South China Sea. Belait, Brunei dan Muara, Temburong, and Tutong are the four districts. The Temburong district is isolated from all other districts and has just a bridge connecting it to the rest of the nation. The whole surface area of Brunei is 5,765 square kilometers. The total number of residents is 460,345 people. With a population of 150,000, the capital and most populous city of the nation is Bandar Seri Begawan. Brunei International Airport (BWN), the main and largest airport, handles about 1.8 million passengers annually. Royal Brunei Airlines, the national carrier with international links, is based out of BWN, the only public airport in the nation. With 78.8% of the population being Muslim and Malay being the national language, Islam dominates the country's culture. The English common law and Islamic sharia law are combined to form the legal system. The Sultan and Prime Minister Sir Hassanal Bolkiah serve as both the head of state and the head of government in this absolute monarchy. Only the head of the village is chosen through elections conducted at the village level. The Brunei Dollar (BND), the nation's official currency, is now at 1.34 to the US dollar. Because the Brunei Dollar and the Singapore Dollar are locked at parity, they can be used interchangeably as money. With an open economy, the nation produces a GDP of about $18.46 billion. With $42,939 per capita, it has a high income. The petroleum and petrochemical industries continue to provide nearly all of the GDP. To lessen reliance on oil and gas, the government concentrates on growing alternative revenue streams including the services industry. There are numerous tourist attractions in the Sultanate of Brunei. The Ministry of Primary Resources and Tourism is generally in charge of overseeing tourism. The Sultan Omar Ali Saifuddin Mosque, the Brunei Museum, the Istana Nurul Iman Palace, Jerudong Park, and Ulu Temburong National Park are a few of the must-see locations. Travelers come to the nation for its pleasant weather, beaches, and stunning scenery, much of which is preserved as national parks. Although the bulk of the 280,000 overnight visitors each year come from Southeast Asian surrounding nations, the number of visitors from beyond the region is rising.
