Still looking for the tie break but a good explanation if the Australian system.

@RegGuy @cmthiede @msbellows @heidilifeldman @mastoreaderio only one candidate gets eliminated at a time. So in your example assuming c3 c4 c5 weren't exactly the same let's say 11.3% 11.4% 11.5% so c3 gets eliminated. His 11.3% is allocated however the voters wanted. Some to each of c1, c2, c4 and c5. Then repeat for new lowest ranked.

Not sure what would happen in a draw where two lowest candidates have exactly same number. I'm sure it's covered in the Australian system. Possibly a coin toss. But very unlikely to have exactly the same number of votes.
