devlin barrett of the washington post.alia is opening up to international travel. fully vaccinated citizens will no longer need permission to leave. our correspondent shaimaa khalil is at sydney airport. it's been a very emotional day here at sydney airport, i'm here at one of the arrival gates and we're just looking at families now arriving. this is one of the flights, people are just making their way back. welcome back! how do you feel? pretty good, good to be home. "pretty good, good to be home". some have said that after waiting for such a long time, it doesn't seem to feel real. people have arrived here to embraces, to cheers and of course, tearful reunions. fully vaccinated australians and australian residents have now been able to come home from overseas, quarantine free for the first time in nearly two years. one of the lucky ones who actually got permission to go, but because my mother died over 1.5 years ago, it was taking that long to get out of the country to sort out her affairs. very emotional at the moment,
