Trials for day/night Tests with the pink ball continued from the previous season.  This season introduced a new bonus point system based on the runs scored and wickets taken in the first 100 overs of both teams' first innings.

As a part of Cricket Australia's campaign for day/night Tests, it included three day/night matches, played with the pink ball.  The separation of the tournaments meant that players in the national Test squad only played two or three Shield matches before the first Test of the 2013–14 Ashes series.
