Am not able to even install the skill because I have a US Alexa/Amazon account. Amazon suggested I leave feedback on here and suggest NAB allows the app to be installed in the US/other countries. SBS has great news so why restrict who can receive it?
This needs to have the US English language added to enable devices not set in AU to access the skill. I imagine some of those overseas would also like access this. Will update the rating when it becomes accessible!
