700MHz Auction announced

"If TPG won the spectrum, it would build a fourth mobile network, and if Optus or Vodafone Australia won the spectrum, capacity and quality across their mobile networks would be increased -- all of which would improve competition, the ACCC said."

Could get quite interesting!

Far from a cheap investment for HTA or TPG though.
