Your Australian mandatory renewable energy target (MRET) scheme might be a useful incentive for new transmission buildouts, as some low solar or wind resource areas (read: grids) won't be able to meet the MRET cost-effectively without importing solar or wind, making new infrastructure investments not only economically justified, but also purely financially (which is a more narrow and difficult criterion).

It's good to see Ausra make advancements. Things are going a bit slower than I'd hoped, though. Do you have any more information about their developments on type of thermal storage, and timelines? It doesn't appear that the larger 177 MWe plant will incorporate storage, in fact it looks like just another transitional pilot. I hope they stick to pressurized water storage, looks best overall, for now.
