Worth noting that US$8.8m prepayment remains or A$12.05m (if calculated using the USD:AUD exchange rate of 0.73:1 from the report footnote in another section).
Therefore, the prepayment has reduced A$3.94m in the Dec-qtr (from A$15.99m).
The prepayment represents 15% of the value of the Lithium shipments whose value must be A$26.26m.
