The Roo to be taken over, page-3

I fear the "national interest test" performed by the FIRB cannot consider any company's individual interest such as WEC's interest to secure their potential damage claims, but only national interest:

"In considering whether investments by foreign government investors are contrary to the national interest, the Government will consider factors including national security; competition; other Australian Government policies such as taxation; the impact on the economy and the community; and the character of the investor (additional aspects are considered for investments in the agricultural sector)."
