Hey Auto... well you know I cannot resist answering those questions so here goes.
(btw - Agree, I am frustrated the Brad left, but luckily the assets are still good)
Current cash balance as of June 30 is $131 million (but I recently was advised that their cash balance is now basically cancelling out the convertible notes), which currently stand at approx AUD $160 million (the notes are in USD and are due Sept 2018, at a 5.5% interest. So DLS have a couple of years to decide how best to deal with it, I am hopeful that by then the AUD will have strengthened again and can be paid down more cheaply.
The Preso is a really good one in answering many of your questions - 2015 Preso
Hedging - (1.64 million barrels in total with a minimum price of US $60)
I can only agree with you that DLS is cheap.
Also, DLS is still offering lots of exploration potential with up to 22 wells to be drilling in FY16. One of which will be targeting a resource of 50mmbo (paid for by BPT).
Anyway, happy to help in any way I can Auto.
