New data showing Telstra's large holding of wholesale services on the National Broadband Network have sparked competition and pricing concerns among smaller internet players.
The Australian Competition and Consumer Commission (ACCC) released on Friday its first data on the telecommunication companies' market shares on the NBN.
The NBN Wholesale Market Indicators report shows Telstra has the most NBN wholesale access services across a number of technologies, including fibre to the node.
Telstra has more than 47 per cent of NBN market share when it comes to fibre to the premise, and more than 58 per cent of market share for fibre to the node, the ACCC's report shows.
The Competitive Carriers' Coalition (CCC), an industry group representing the nation's smaller carriers, said the report is concerning, especially given Australia's internet services are among the most expensive in the world.

CCC spokesman David Forman said new technologies, in particular fibre to the node, appears to have given Telstra an advantage and threatens future healthy competition.
"Telstra has more control over the transistion to NBN since the introduction of new technologies after the last election," Mr Forman said.
"There is the potential for Telstra to take even more advantage over its competitors which means less competition and higher prices (for consumers)."
The ACCC report said Telstra was acquiring the largest number of NBN wholesale access services in Australia, followed by the TPG group, Singtel Optus and the M2 group.
