speculation of action in the cooper

I was just reading the deals section of the FIN and there is a decent write up on additional overseas companies who may be looking to wrap up unconventional gas in the Cooper.
Potential targets included both Beach and Senex, with the tips going to Beach given the recent data room opening for a shale farmout.
The article aslo threw about a number of $500m for Beach's 30% farmout. If that was the number what does it mean for Senex? (Tui?)

Thinking about selling a few other shares and going super long SXY, after all who needs diversification right?
