sms to my mobile from this number say MyGov and a link URL which is definitely sus.

I got an sms from this number on 28 October as well also stating MyGov and a weird looking link. I didn’t click the link but I did got to my gov and logged in and found I had a new message about a tax return from 12 years ago. I got another message today from 0404 625 961 saying MyGov and a weird link. I haven’t yet logged into myGov today to see if there is a new message. The sms look sus and they only happen at random times on weekends.
