What are the procedures for Australian parents to transfer from 103 to 143?

Hello, I'm glad to answer your question:

103 can be directly converted into 143, and there is no need to pay the visa fee, because the application fee of 143 is more expensive than that of 103, so you only need to make up the missing money:

Trial time of visa type application fee

103 The queue of A $2370 takes almost 13 years.

143 3520 Australian dollars +43600 Australian dollars for about 2 years, 1 year and a half.

103 can be directly converted into 143. You only need to pay the first application fee of 1 150 Australian dollars, and then pay the second application fee of 43,600 Australian dollars after the immigration office informs you of the physical examination. 143 parents' immigration expenses are more expensive than 103, but the trial time is close to 1 1 year. I hope the above answers can help you, and I hope to adopt them. Thank you very much!
