The Historic Houses Trust manage a few museums around the city, and it's a good idea to check out the site before you go. In any case, their head office is in the historic Mint building on Macquarie Street, where you can buy tickets for their museums as well as look at the beautiful Georgian architecture.
The Trust manage some of Sydney's more fascinating colonial buildings, and will give you an insight into the difficulties posed to the early colony. There are two harbourside mansions in their 'collection' – Elizabeth Bay House, a fine regency villa, and Vaucluse House, that began life as a cottage in 1803. Both have educational displays and antiques on site, and in particular Vaucluse House is set within beautiful grounds.
They also manage the Museum of Sydney, which is in the city. This museum looks at the interesting history of Sydney from convict times through to the present. A short detour from the Museum of Sydney would be the Hyde Park Barracks, which shows life as a convict in the early 19th century.
Most venues have a book/gift shop, and some have cafes.
