Just to answer my own question I see in the Australian article about Origin sales (see Senex thread) that Morgan Stanley puts a value of $330M on the Origin stake in the SACB JV so about $2.5 Billion on the whole lot - pipelines, plant and fields. I'd be surprised if that value was attainable though given the weakness of the sellers.
