Plenty of people flocked over to the park to witness the official opening of the mural on Thursday, July 11 as part of NAIDOC Week.

NAIDOC Week started on July 7 and Goulburn Place Plan's Aboriginal community development officer Cr Alfie Walker said the theme for the week is voice, treaty, truth.

"It's all about the active reconciliation of us getting together and opening this Aboriginal mural," Cr Walker said.

Family and Community Services (FACS) approached Goulburn Mulwaree Council asking for support for the installation of Aboriginal artwork at the handball wall as part of their Goulburn Place Plan project.

FACS, which fully funded the artwork, worked with the Pejar Local Aboriginal Land Council, which supported the project, to approve a design.

Pejar Local Aboriginal Land Council chairperson Chelsea Boney explained that the mural is the Aboriginal Dreaming Story of how the Wollondilly, Cox, and Guineacor Rivers, Wombeyan and Jenolan caves were created.

"The painting is called Gurangatch and Mirrigan," Ms Boney said.

"The different colours represent Gurangatch who had scales resembling the colours of the rainbow."

A lot of the local community was involved with the mural including local artist Aryssa McAlister who painted it with a lot of young people in partnership with the Pejar Local Aboriginal Lands Council.

The opening began with speeches from Cr Walker, Clint Ramsay from FACS and Ms Boney before a smoking ceremony was conducted.

The official party, which included Goulburn Mulwaree Mayor Bob Kirk and Member for Goulburn Wendy Tuckerman, then cut the ribbon to signal the official opening of the mural before Ms McAlister cut a cake with an edible picture of the painting.

Mission Australia's area manager of south eastern NSW and ACT Daniel Strickland felt the mural was a fabulous contribution to the local area.

"It brings colour, history and beauty to Leggett Park," Mr Strickland said.

"The artwork tells the fascinating creation story of our local landscape and is a wonderful celebration of the rich culture and heritage of our Aboriginal community."

There was also a free sausage sizzle for those involved.
