The name is a reference to holiday gifts.
A 'Christmas Box' in Britain is a name for a Christmas present. Boxing Day was traditionally a day off for servants and the day when they received a 'Christmas Box' from the master. The servants would also go home on Boxing Day to give 'Christmas Boxes' to their families.
The 26th of December actually has its origins in a much more noble (and less painful) practice. It is said to have begun in England during the Middle Ages, when the servants of wealthy families had to work on Christmas Day. (Come on, did you think those princes and princesses cooked their own Noche Buena? Of course not.)
To make up for it, the said servants were given the day off the morning after to visit their families and to celebrate Christmas as they wished. Before they left on their respective outings, each servant would receive from their master a box containing gifts, bonuses, or even leftover food from the previous night’s feast. In some variations, these Christmas boxes also referred to the ones that tradespeople would collect from their clients on the first working day after the holiday in gratitude for their services throughout the year.
In another variation of the origin story, Boxing Day refers to the boxes placed inside the churches to collect money for the poor. These donation boxes are then opened the day after Christmas and distributed among the less fortunate. (Another spin on the tale has a sealed box onboard sailing ships for good luck. If the ship was lucky enough to complete their voyage safely, the box was given to a priest, who would then open it up at Christmas so that the contents could be given to the poor.)
So, why does Australia celebrate Boxing Day while we don’t? The answer’s quite simple: the practice originated in the United Kingdom, in England particularly, so it spread throughout all its colonies. Since Australia is counted as one and continues to be part of the Commonwealth, the Boxing Day tradition naturally figured into its overall culture.
