The problem is that the RC3 database is badly programmed.
There are big problems with Australian players who are double in the Super Rugby Teams and the Australian National Rugby Championship.
You see it when you play against the computer in career mode and look at your opponents' squad.
Save your time and wait for RC4 or something like that next year in the World cup year.
I've tried a few things, and it's very frustrating.
That's why I unpacked Rugby Challenge 2 and changed it.(It's better programmed)
First, I loaded the bric mod. As a fundament.

Then I have created a database with the players from 2013-17
The player values are adjusted to their strongest time in this period.
It's a little fantasy but you have fun.
The national teams are ready.
The European leagues are ready.
The Super Rugby League isn't finished.
Because the players are double, if you want to play this league you have to delete the twin players in the European teams.
Here is the database:
