This season marked the introduction of the Block to the Australian version. Though it has been used on many other versions of the franchise, the Australian series allowed each coach two Blocks and required both the blocking and blocked coaches to have turned their chairs before it could be used.
This year, two of the All Stars were artists from other international versions of The Voice franchise, while the others were from previous Australian seasons.
This is the first Australian season where the coaches are unchanged from the previous season.
