Given that the market looks forward (or at least it ought to) , Lets have a guesstimate at TIG's cash requirements Jan 1 2019 to 30th June2019.

Let's assume that cash burn for this period is roughly the same as that for 2018

To block this out we can start at cash 31st Dec 2017, add income for the 6 months period (incl $14.58 mil AUD bank loan) and then subtract cash
at the. 30th June 2018. Rather than bore you with the sum, the cash burn is $18.338 mil mil AUD.

The forecast cash for 31st Dec  is $4.5 mil AUD .......($4.791 AUD on the 30th Sept minus $491K cash burn Dec Qtr)
So the cash needed to see TIG through to 30th June  based on 2017 figures would be $18.338 mil

IMO,  TIG will need bridging finance  of $13,838 mil AUD to see it through to 30th June 2019.
Or:
If TIG defers the bank loan repayment of $10.589 mil which it intends to repay in the Dec Qtr until next Fin Year, then it will still need 
$3,25 mil bridging loan, IMO.
