The old grocery store is one of only three museum stores in the world where the contents have been preserved in original condition.
The collection contains more than 100,000 relics such as rusty tins of World War II, Lucky Hit tobacco and long-forgotten Australian brands like Brasso, Super Rinso and Chief floor polish.
The store opened in 1871 and ceased trading in 1972 complete with trading records and stock dating back to the 1890s.
