I actually just did this flight a few weeks ago!

The movie selection is more than sufficient to get you through 14 hrs. About 7-10 recent hollywood movies, a handful from the early 2000s, as well as a few classics. I never found that I was running out of things to watch....

They do give you 1 (small) bottle of spring water with the first meal service (in Y). For the rest of the flight they just pour you some bottled water. Dasani, I believe. If you're ultra particular about the water you drink you would probably be best to buy something at the airport.....

For charging, I know 100% they have canadian plugs. I'm not sure if it's compatible with Oz ones. I'm sure someone else will be able to comment.

Enjoy your time in Canada
