Gas price soars as Santos signs domestic deals SANTOS has signed east coast domestic gas deals for beyond 2015 at close to export parity as $70 billion worth of liquefied natural gas projects at Gladstone come closer to production, exposing Australian domestic gas buyers to export prices. Santos chief David Knox, who delivered a better than expected full-year profit report yesterday, said gas deals were already being signed at the "higher end" of a $6-$9 a gigajoule range, up from current prices of $3 to $4.
