Just as described in "Invoice requirements" above for the EU, in Australia, if GST is part of an invoice, the total GST paid must be itemised. In addition, the invoice must have the words "Tax Invoice" on it.
A business can elect to account for and pay GST either on a cash basis (actual money moving) or accrual (invoices and purchase orders).
