I moved to work in Australia about 10 years ago, got there a permanent Australian visa as an employer-nominated skilled migrant, and became an Australian citizen by conferral about four years ago from now.
A couple of weeks after making the Australian citizenship pledge and getting my Australian citizenship certificate and Australian passport I moved to Europe, and I have never been back to Australia since then.
My question is in the title of this post. I am asking this question because I am getting worried that my Australian citizenship might be revoked. The source of my worries is that I vaguely remember reading an article saying something like, "Those who obtain Australian citizenship merely for convenience of travel and do not intend to permanently live in Australia can be stripped of their Australian citizenship." I read that article many years ago and am unable to find it now.
I did research on the Internet, but have been unable to find a definite answer. On the one hand, I found no mentions whatsoever of people stripped of Australian citizenship just for a long period of absence from Australia, and I found no mentions of any requirements to stay in Australia in order to retain Australian citizenship. On the other hand, there seems to be a legal avenue to strip people like me of Australian citizenship: I recall that I had to explicitly confirm in my citizenship application that I intended to permanently reside in Australia, and I am afraid that moving to Europe from Australia just a couple of weeks after getting Australian citizenship might be seen as strong evidence that I lied about my intent to permanently reside in Australia. Many sources on the Internet say that Australian citizenship can be revoked in cases of false or misleading information in the citizenship application.
The actual reason for moving to Europe was that I had a good job offer from there, had been struggling already for about half a year to find a good job in Australia, did not want to take a low-skilled job like a salesperson at Coles or have a long unemployment gap in my CV, and was running out of my savings. I never had plans to permanently reside in Europe, and I accepted the European offer just to avoid a long interruption of my career as a highly skilled worker, to fix my finances, and to buy some time to figure out how to develop my career further.
It is very important to me to retain Australian citizenship, especially given that my career prospects in Europe do not look good and that I am unlikely to get a permanent residence permit in Europe in the foreseeable future. I have retained citizenship of my country of origin, so I am a dual citizen, but my country of origin is a poorly developed country whose cultural values I do not share, and I do not want to end up living there at all. I consider Australia my home, so to speak.
So I would be very thankful for any information regarding my question stated in the title of this post.
