Split the ladder into five groups:
1-4
5-8
9-12
13-16
17-18
The top four groups play one team from each group including their own twice and the bottom two play each other twice plus two teams from one group and one from every group except the top four.
The top four groups play an extra game against a random team from any group, except 17-18 cannot play a team from 1-4 twice. That way you don’t get a Geelong v North double up etc.
Not sure if it works or not. It could be tweaked that top 8 teams can’t play two teams from a group outside the top 8. I think.
Edit: apparently I didn’t make myself clear enough but this system is for the five return matches only. Everyone would still play each other at least once.
