csg to lng project will go ahead

The 40% resources rent tax won't hurt CSG to LNG project much, because those projects are not very high margin business like iron ore project, and CSG royalty(10%) is higher than iron ore royalty(2.7%-7.5%).

According to Citigroup report
"The tax rate for the Australia Pacific LNG project, led by Origin Energy Ltd. and ConocoPhillips, may climb to an average of 44 percent because of the overhaul, from 41 percent," the May 2 report said.
Compare with BHP australia business
"the RSP tax would increase the tax take from its Australian profits from around 43 per cent to 57 per cent"

I am still very confident those CSG to LNG projects will go ahead.
