ATTN AUSTRALIANS: Weird Emergency sms message from government.

I realise this could isnt that big of a deal, yet i found it all quite strange still, and it just makes me wonder where this is leading. Today i recieved a strange sms from the government. Now i live in South Australia, so im not sure how many people recieved this whether your in SA, or in another state. The phone number i recieve it from was: 0444444444

And it reads:

"TEST MESSAGE from SA Government as part of ongoing emergency preparedness NO ACTION OF RESPONSE REQUIRED More info on warning system www.emergencyalert.gov.au"

Of course, this could be for potential bushfires, natural disasters, terrorist attacks whatever. I dont know. I just think its a bit off, as this hasnt happened before, and only feels like its coming to a head. Who knows how this service may work.

I just thought id post this as its a bit unusual, and well... thats what the internet is for, spreading random information! So, heads up!
