Can you play American DVDs on an Australian DVD player?
US is NTSC television standard. Australia is PAL television standard. The two are totally and completely incompatible. The only way to play one on another is to use a very expensive multistandard player and/or TV. There is also the issue of DVD region code settings. US=1, Austalia=4. But those are easier to get around. However, there is no getting around the television standards. Without a multistandard TV, your only other option is to use a computer to make a copy. It reduces the TV standard to basic RGB video and re-encodes it to the other standard, and most copying software has that capability. They can usually bypass the region code, too. What they can’t bypass is many copy protection schemes on the DVD, which often requires a separate software.
