Gina is NOT in the Business of buying cashflow ... from gas sales to Santos. She already has her own cash cow, she just needs energy security to keep feeding it.
She is in the Business of energy security, buying up un-contracted gas, to provide energy security for her Money Maker.
She, like many in business are worried about Socialism, which is creeping its way into WA and VIC, which is sure to undermine her money maker in the future. She buys uncontracted gas, so she can operate independently of whoever is in Gov't pulling the latest Woke Climate Change leavers and pandering to the noncontributing folk. Apparently, they vote, so you have to tell them what they want to hear, if you want to keep your Job.
That's why Gina won't buy TPD, She'd access Senex's gas, if it wasn't on the other side of the Country.
STX will remain patient, OH and don't expect and gas flows / cash flows soon. Plenty of legitimate reasons why future delays are likely.
