The newly-established 59Racing squad, which is based in Melbourne, will field its 720S in the full Australian GT Championship, which kicks off with the F1 support event.
The team takes it name from the race number of the McLaren F1 GTR that claimed overall victory at the 1995 Le Mans 24 Hours.
Its 720S will also run race number #59 and will compete in McLaren's iconic orange colours.
Fraser Ross, a frontrunner in the championship with the McLaren 650S GT3 over the past two seasons, will drive the car in the full championship.
McLaren Automotive motorsport director Dan Walmsley said: "It is great to welcome another new team to the McLaren customer racing family, with the launch of 59Racing, which will be the first of our teams to take to the track in competition with the 720S GT3.
"Premiering as part of the F1 race activity, with 59Racing running in its home race, is a fantastic platform for the team and McLaren alike."
There are four Australian GT races on the schedule over the Melbourne weekend.
59Racing will also field a 570S GT4 car in Australian GT series.
