The Government has increased funding for adult cochlear implants by $1.6 million.
The additional funding will double the number who receive them to 40 a year.
Health Minister Tony Ryall said the total funding would reach $7 million.
"Currently adults can wait around two years for a cochlear implant. However, some wait longer depending on their clinical priority.
"We have invested nearly $7 million in one-off funding in the past four years to reduce how long adults wait for their implant. However, the Government thinks greater certainty is needed rather than peaks and troughs of patients receiving implants."
