Australian parents immigrated from 103 to 143. Do I need to pay the visa fee again? Category 103 visa fee will not be invalid, will it? thank you

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:

Visa type, application fee, trial and time:

103: 2370 Australian dollars, and the queue takes almost 13 years.

143: 3520 Australian dollars +43600 Australian dollars, about 2 years, 1.5 years can come down.

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.
