The Aussie says, "Now..." at 0:45 in the video. Then again at 1:53, what is he saying?
Which movies should do the job for understanding the Aussie accent clearly?
Australian accents can be roughly divided into three groups.
For most visitors, understanding the "general" dialect is most important, as most speakers are able to "code switch" and move from the broad accent to a general accent, if necessary.
There are some great Aussie movies "Pricilla Queen of the Desert", "Muriel's Wedding" and of course "Crocodile Dundee". More recent films include "Snowtown" and "Animal Kingdom"
