I noticed a few days ago that Google have made the "Ok Google" hot word work in Australia! This means if you have an android device and are using the Google Now Launcher, you just need to be at the home screen and say "OK Google" to give it voice commands! So if you have the Google Now Launcher, try it now, unlock your device and say "OK Google, What is the current weather?" And be amazed as it replies to you with the current weather for your area. There's many other functions you can ask it to, just play with it and have fun!   https://play.google.com/store/apps/details?id=com.google.android.launcher
