We're in the queue for 143 also, having lodged in 2019 and now expecting to have to wait longer than first advised, so are now looking at applying for 870. My daughter who has citizenship is looking to lodge sponsorship forms in July this year. We are visiting for three months in September, having not seen her since July 2019 thanks to Covid. Our first grandson will be now turning three shortly! Although facetime is a godsend, a computer screen can never replace that physical emotion.
We also have a son who is a Canadian citizen and so for us it has been extremely hard over the last two years. As parents, we are extremely proud of our children and what they have both achieved and like Linda, would never ask or expect them to return here to support us. They too, have made sacrifices in order to pursue their dreams. I sometimes feel that the Australian Government is blindsided by their 'medical concerns' and 'lack of contribution' when deciding the quota of Parental visas, especially when the cost is so high financially but more importantly mentally. My husband and I are committed to seeing our application through and one day, hopefully in the not so distant future, we will be raising a glass to them & thanking them for giving us the opportunity to recoup some of that physical emotion that we have missed so much.
Good luck to everyone, which ever route you choose to take.
