Seems to be a scam. Caller leaves a text message telling you that your MyGov details have changed, and if you didn't change them, then visit a link provided. I visited MyGov and there was no changes made, and the system told me I hadn't even logged in for months. this means the caller who left the text was lying and the link is most likely a scam. Don't fall for this peeps, always check before clicking on that link :)

I received the same message telling that MyGov details have changed, and if you didn't change them, then visit a link provided
Firstly mygov is spelt incorrectly.
Secondly the website quoted on the message is xxxxxx.net. Government websites never contain xxxxxx.net

I recieved a message from this number claiming to be from MyGov and wanting me to update my information
