Sydney was the first colony established by European colonists in Australia, and Australia's first Governorate was built in Sydney. The site of the First Governor's House is located in the front square at the northern end of the Sydney Museum on Phillip Street and Bridge Street, and the First Governor's House has been maintained from 1788 to 1945. Instead of including the remaining foundations of the Governor's House along Bridge Street in the museum's interior, DCM Architectural Design left them on the periphery of the museum as open exhibits, while restoring the floor of the Governor's House through granite paving. Thus, the remaining foundations are easily discernible, with the restored flat surfaces of white granite and the rest of the black granite. The paving of the square can be removed at any time to show the remnants below. In 1816, the then Governor of Australia planned to build a new Governor's Mansion, but it was not built until 1845, and the new Governor's Mansion, which was completed in 1845, is the Governor's Mansion in the Royal Botanic Garden. 1901 Australia was independent in Melbourne, and the Governor of Australia rarely used this residence again. The State Government has since reclaimed the castle as the Governor's residence in NSW, also known as the Governor's House, but the Governor's House in NSW. It was opened to the public until 1996, when the Governor's Office moved out of the house and is now one of Sydney's major tourist attractions. The former colonial government residence, which was once a part of Australia's colonial past, has been renovated and the Governor's House remains the same as it was more than a century ago. The Governor's House, Elizabeth Farm and Pilot Farms, witness the beginning of Australian history. The designer of the Governor's House is the royal designer of King William IV. He has participated in the design of Windsor Castle and Buckingham Palace. The interior decoration of the Governor's House is completely British, with conference halls, ballrooms, study rooms, dining rooms, living rooms, etc. Portraits of successive governors are hung on the walls of the foyer, and all window glass is bulletproof. Therefore, the correction here is: 1. The site of the First Governor's House is located in the square in front of the Sydney Museum (1788~1845); 2. The new Governor's Mansion in the Royal Botanic Garden was the Governor's Mansion in Australia from 1845 to 1901; 3. The New Governor's Mansion in the Royal Botanic Garden was the Governor's Mansion in NSW after 1901.
