At one point in the film, a character says that employees to be fired should be given their "pink slips." The film takes place in 1830s Australia. An article in the New York Times dates the earliest use of the term "pink slip" to 1910.
The opening narration declares that "In 1770 Captain Cook discovered Australia". While James Cook led one of the first British expeditions to Australia, other European explorers had visited the country before him.
As the characters gather for the dinner party, fairly early on in the film, the camera tracks backwards across the dining room. The table has been pushed into the path of the camera by the time it comes into view, but the candlesticks are still shaking severely from the jerking appearance of the table (their shaking lessens as the take continues).
