Whoever you are paying these charges to, is the Supplier you select (not - “I need to select a customer first”)
In this case, you should be taking up those charges via an Expense Claim, not via a Suppliers Purchase Invoice. Under Setting - Expense Claim Payers you would set yourself up and after the Expense Claim has been created you would transfer the Expense Claim to the ‘Loan from Director’ via journal.
However, if you prefer to record these charges under the Supplier, then do a normal Purchase Invoice but take up the “payment” via a Journal - Debit Accounts Payable + Supplier + Invoice and Credit ‘Loan from Director’
Ok, the demonstration example is for worldwide use, however for Australia there is a special tax code.

- You shouldn’t be using Journals for purchases, that is what the Suppliers and Purchase Invoices tabs are for. 2) You don’t put GST entries directly to the Tax Payable account, you use the Tax field and then the amounts will automatically end up on the BAS.
