How well were the animals treated in this film?

Reading what people here have said about The Dish has me intrigued, and I'd like to see it, but I don't personally know anyone who's seen the film, so...

How well did it appear that the animals (I'm presuming sheep, since it's set in a sheep farm, and any others) in this film were treated?

I'm often appalled at how carelessly or cruelly animals are treated in movies, and while I realize that what we see on-screen is not a completely reliable indicator of how animals in a movie are ACTUALLY treated, I'm interested in hearing any impressions about scenes involving animals.

Anyone who knows anything about the production standards could really help me out, but I'd appreciate hearing an opinion on this from anyone who has one.

Since this was an Australian movie, I don't think American Humane monitored the production of the film (I didn't find it on the big list on their website), and I don't know if Australia has any similar group or mechanism to ensure the decent treatment of animals in movies.

Any info (or opinion) would be appreciated!
