No that isn't correct, if you look at the titles they are different and if you go onto either Australian Television's website
http://www.australiantelevision.net/city_homicide/series3.html or
http://www.tv.com/city-homicide/show/74552/episode.html as Aliyua mentioned up above, you will see that there are a total of 42 episodes for 3 seasons.
Australian Television aired 13 episodes for Season 1, 22 episodes in Season 2 - ( VIPTV, only uploaded 14 episodes and the titles and episode numbers are correctly listed) and so far, 6 episodes for Season 3
So, if what you are saying is that episode 2x15- 218 are actually season 3, then they are titled incorrectly and we are still missing 4 more episodes for season 2, and we are missing the first 4 episodes for season 3
or we are just missing the 8 episodes (listed in red above) that aired in February and March of this year or - one way or another we are missing 8 episodes.
We are now into Season 3 if you look at the dates after the titles, I listed when they were aired by Australian Television The list I provided is all 42 episodes, listed by season and episode number, title and date it aired ( + the next episode due to be aired on September 14th.)
I've been saying this since February, but I can't seem to get anyone to understand. I hoped that by listing all 42 episodes it would be clear and someone would straighten out the confusion and upload the missing episodes..
