Landed Cost - VOTI
Traditionally GST on imports to Australia is not charged by the supplier but by Customs. So historically there will be no GST in the supplier invoice where the supplier is a foreign creditor.
You need to use the VOTI tab to enter GST charged by Customs. You just enter the GST as determined by customs and Jiwa works out the value of the taxable import and the postings.
The ledger account on the line should be a P&L account. In the resulting journal there will be a debit and credit to the P&L account for the same amount and the debit has the BAS Code attached. The other two lines of the journal will be debit GST Ledger account with BAS Code and credit to the Creditors Control account. That has the result you're after in the BAS report.
