I have some background in tech, I've been trying to personally investigate this further, the suspicious links are four letter combinations followed by a TLDs of (dot) info. All the links redirect to the official www.servicesaustralia.gov.au domain.

The domains themselves are ran from China the hosting company is Tencent or Alibaba, it could be a targeted attack by a state sponsored hackers but i don't know.

I got text message saying mygov

I received message that has a link supposedly come from mygov but the address looks suspicious. I didn’t click it. MyGov messages should come into my myGov inbox not from random text messages.
