If you want to keep it simple, place six or more numbers above the line. Here is my suggestion for the first six parties:

Sustainable Australia in particular is a very good party with a lot of good ideas and similar views to myself. I am also quite comfortable with CountryMinded and Katter's Australia Party. After that it became increasingly difficult to put more parties down. If you prefer Labor (code N) over Coalition (code F) or the other way around, feel free to put your preferred major party at number 7 or replace Health Australia Party for 6.

You can choose any six (or more) you like. But I put six down as a starting point.
