I used a combination of sources to gather this information, including historical records, official websites of museums and libraries, and general knowledge databases. Some specific sources include:
- The official websites of the Australian National Maritime Museum (www.anmm.gov.au), the State Library of New South Wales (www.sl.nsw.gov.au), and the Museum of Sydney (www.museumofsydney.com.au).
- The Australian Government's Department of Infrastructure, Transport, Regional Development, and Communications website (www.infrastructure.gov.au) for information on the Sydney Harbour Bridge.
- The Sydney Opera House official website (www.sydneyoperahouse.com) for details about the venue.
- General knowledge databases and historical archives for specific dates and events.
It's essential to note that while I tried to provide accurate information, some details might be subject to variations or inconsistencies in historical records. For the most accurate and up-to-date information, it's always best to consult primary sources or refer to expert historians.
Direct links to specific pages on websites might change over time, and I don't have access to real-time information. However, you can typically find this information by searching for "Sydney" and "5 April" on the websites I mentioned earlier.
Here's a general outline of how you can search for the information on some of these websites:
Remember that some of these websites may require you to navigate through their menus and search for the information using specific keywords and phrases.
