AGL (and others) are seeking a price rise because they can export their gas for more money than they get paid here. So they want price parity, which is fair enough.
However, when things turn (and they will!), these same companies may well come to the government of the day asking to be 'rescued' with taxpayers money! Has happened before.
The only sensibel thing to do for any governmetn is to preserve a share of production for domestic market at set prices, prices that allow for a modest profit. Just as now.
Most civilised countries in the world do this.

There is no point in allowing (or fostering) wholesale development all over the country in the vague hope that it will bring prices down. Who will stop MEL to export their gas? No one.

And, mind you, one (maybe conventional) well, like Rosella (the proof is till out whether fracking will be required) doesn't make a viable operation. That will require dozens, if not hundreds of wells. Most of then unconventional. Food for thought, eh?
