There is a stuff up between the cash figure at the start of the report and those in the 5B Appendix.
They appear to have treated the Cash & Equivalents for $17.387M plus late receipt of A$7.5M for bullion on 28/7/23 in the 5B as US$ and then converted them to A$ for the figure of A$36.2M (US$24M) at the front of the report.
I think we need to take the 5B figures as the correct ones.
