"The court case stemmed from an October 2015 ruling by the ACCC that lowered the regulated price Telstra charges its wholesale partners to access its fixed-line copper network by 9.4 percent."

I assume Telstra was already charging the lower rate, so no change to current costs for TPG/VOC/Others (would like to be wrong though).
