CGA President Ben Houston insisted that Cator, Moneghetti and Walker were well worthy of their life membership status.

"Congratulations to Rhonda, Bill and Mona [Moneghetti] who have all made their mark on their sport and the Commonwealth Sports Movement in Australia," Houston said.

"From the grassroots to the participation in the Games as athletes and leaders and in Bill’s case, his enduring legacy of the CGA Foundation which continues to underpin the financial stability of CGA and with it the support provided to member sports and athletes.

"They are all deserving of the honour of life membership."

Australia is one of the leading nations in the Commonwealth Games.

The country leads the all-time medals table, and has held the Games on five occasions, including the most recent edition at Gold Coast 2018.

The multi-sport is set to return to Australia after this year's edition in the English city of Birmingham, with the state of Victoria awarded hosting rights for 2026.
