Nine outdoor acrylic hard courts and four indoor acrylic hard courts are being resurfaced ahead of January's Canberra International, while a new northern grandstand will be built for the event.

Tennis ACT officials hope the tournament will provide a boost to those eyeing the Australian Open.

LED lighting upgrades will commence on centre court, three outdoor courts and four indoor courts.

New Tennis Hot Shots courts will be built next year with the existing ones to be converted to a full sized practice court.

"We have always had such positive feedback from players around the world class facilities we have here in Canberra and these upgrades are going to take it to the next level," Tennis ACT chief executive Kim Kachel said.

"The upgrades, in particular the lighting are going to provide us with more flexibility around the scheduling of matches throughout the tournament.

"We are excited to deliver the second stage of the redevelopment of the Canberra Tennis Centre in time for our bolstered event in January.

"The upgrades will be a great result for fans too with increased capacity and seating options.

"We are sure they will love the night session matches and the extra seating available in the northern grandstand."

The Canberra International begins on January 6 with a men's ATP Challenger 125 and women's $36,978 ITF World Tennis Tour event.
