Didn't see it, was locked up at work.
Never seen a contrail over Perth during the day, not that it's impossible, just that planes rarely fly high enough in this part of the world.
Ususally when we see them here, they are either heading in to land or have just taken off....
Only ever spotted one at altitude over Perth in my 30 odd years, and that was a full moon night so could just make out a slight trail. Figured it must have been heading to South Africa from Syd or Melb.
