Traveling abroad with a group in Australia, what will happen if you don't come back?

If you travel abroad with a group and don't come back, it is "illegal detention" in an easy-to-understand sentence. Law enforcement personnel of the country where the detention place is located have the right to arrest and repatriate. After returning home, they will be punished by the relevant domestic departments in accordance with relevant laws and regulations. If repatriated, the passport will be stained and may be banned from illegal entry in the future. And applying for visas from other big countries, such as Canada and the United States, will also be affected. Even if you can work illegally and have no legal status, your rights and interests will not be guaranteed.
