The National Parks and Wildlife Service has defended an $11 increase to entry fees to the Kosciuszko National Park.
The price rise will be phased in over the next two ski seasons, eventually raising the gate fee from $16 to $27.
Some of the park's operators are concerned the price rise will force tourists away.
But the director with the National Parks and Wildlife Service, Alistair Henchman, says the increase is needed to fund upgrades to the park.
"The fees haven't increased apart from CPI [Consumer Price Index] increases in something like 10 years and this is a significant increase," he said.
"We recognise that but we've got an undertaking that all of this increase will be spent in Kosciuszko National Park."
