Ann: Significant Upgrade of Kingia Gas Discovery, page-141

I agree.
Beach are most likely to make an early-bird takeover as they already have a whole load of data with which to assess/cross-reference Strike's existing results. But they will wait until after flow rates. No board of directors will back <$500 million takeover bid without making sure the gas flows. If things go pear-shaped, it would be career suicide.
Another reason I think Beach/Mitsui will want to take out Strike/WGO is to prevent them from flooding the WA market with cheap gas. By taking out Strike/WGO they don't have to worry about them undercutting their prices on their existing production (thereby forestalling a potentially $hundred million write down of their existing WA assets) and then use the new reserves to start planning an LNG export business (with enough acreage to farm-down to the monster O&G companies, like the CBM companies do with BG/Shell, for example).
Another way of putting it, Beach and Mitsui will want a strangle hold on this potentially new market.
Long-term, however, (i.e. once those outside the region have had time to analyse the data) anyone might launch a bit for Strike/WGO. Again, Beach/Mitsui have an incentive get in before this happens.
