A well reviewed set top box link
Here's the basic spec rundown:
Supports up to 4K video (though Foxtel Now only streams up to Full HD)
Runs Android TV (Android Nougat)
Built-in free-to-air tuner
4K Chromecast support
Google Play app for downloading movies and TV shows
8GB on-board flash storage
Infrared/Bluetooth remote control
802.11ac Wi-Fi
HDMI 2.0, Ethernet and Bluetooth 4.1 connectivity
Voice support in remote (though no voice capability at search)
Not really a great deal considering Foxtel gives 2 months of all the channels free when purchasing from them directly for $99.
So if anything this costs an extra $200
