what if I told you to add up HP1 ($1.7m aud), HP2 ($2m aud)...

what if I told you to add up HP1 ($1.7m aud), HP2 ($2m aud) receivables due in December ($4m aud) as well as $1m for r@d rebate.

then for your OPEX of $2.95M. to sensitise it's - DOUBLE IT to $6m.

then remove the interest received, tax incentives and others totalling $495k for further sensitisation.

net inflow of cash is $2.7m noting:
.I've doubled opex which is beyond ridiculous for you but to show you how wrong you are. or conversely why not just remove the $4m in receivables you're worried about and keep opex as is... still get a net inflow.
. I've removed $495k from other sources of income

I suppose it pays to read the quarterly in full. to that extent you'd also recognise they've stated the production costs included deposit outlays for future production runs (ie they've taken this opportunity to sure up future production runs and incur the cost now).
