Australia 402 visa, would like to ask if there will be a fee if the visa is not passed, about how much?

All Australian visas have an application fee, which is more or less non-refundable, regardless of success or failure, because this is the application fee, which is paid to the visa officer and the Australian Immigration Bureau to make efforts to review your visa. Visa 402 is a visiting scholar visa, regardless of the agency fee, and there is an application fee of about 2000 RMB. Regardless of success or failure, there is no refund.
