CoinSpot processes AUD withdrawals throughout the week.
This usually means the AUD withdrawal is processed within 3 business days of submitting your withdrawal request. Once your withdrawal is processed, the transfer is subject to the standard domestic transfer times.
If you make multiple withdrawal requests in the same day, you may only receive one withdrawal a day, meaning there could be additional delays to your subsequent withdrawals.
Please make sure that your bank details are correct on the account -> settings page and that there are sufficient funds in your AUD wallet at the time the withdrawal is processed or your request may be cancelled.
