Just as a matter of interest Apache paid over $40M to get into 25% of WA-351-P (Tallaganda) and since then Bunyip-1 (6 km further South than Tallaganda) has had success.
Zola/Bianchi-1/Antiope appear to be part of a quite large structure and could contain 2 to 3 tcf (Woodside's Pluto LNG Plant was built on the basis of only 3 tcf of reserves). TAP has 10% of of WA-290-P (Zola) so I don't know what value you would put on that.
Then of course there is Prometheus/Rubicon (both relatively large - multiple hundreds), Maitland and Taunton
