When you start with movies, watching an English language movie with English subtitles is a good choice, but please bear in mind that sometimes the subtitles do not exactly match the language spoken in the movie. You can also download subtitles from the internet; look for the .srt file extension. Make sure you match the correct subtitles to the movie. I once unknowingly downloaded American subtitles for an Australian movie, where the language had been changed to suit the American audience. They did not match my Australian (original) version of the movie at all!
One thing I recommend is to first watch a movie you know well, so that you can follow the plot without getting frustrated if you can't understand every word. Then, watch a movie or TV series about a subject area you are interested in. For example, if you like building and architecture, try watching Grand Designs. If you like cars, try Top Gear.
Here is a list of my favourite Australian movies and TV programmes for listening to English language and observing Australian society and culture. After watching your favourite blockbusters, try these:
1. The Castle (1997)
2. They're a Weird Mob (1966) (old, but good)
3. Australia (2008)
4. The Cup (2011)
5. Crocodile Dundee (1986)
6. Packed to the Rafters (2008 - 2012) (TV series)
Happy viewing!
