That is the roster worked in UK and Middle East. One group in Brisbane worked something similar but with day shifts every few weeks (could be more these days). I am not a current employee but your rosters are based on a fatigue score maximum value and not less than 10 hours between (and some other technicalities). Afternoon, day, morning and back same night then 2 off was the traditional way of doing things.
StATCLover, I see you asking for details about the future EBA but it seems you have not read the current one properly.

Page 19 onwards refers to work hours. Create what ever you (they) want based on those rules.
In my opinion it is a bad idea having duty hours covered in the Enterprise Agreeement as they become a bargaining chip every 3 years. They should be contained in the Civil Aviation Regulations.
