Ben Roberts-Smith’s parents, Len and Sue Roberts-Smith, said they were proud to see their son’s name attached to the Scarborough complex.
“Our son has been through so much, and our family knows deeply that the challenges faced by veterans and their loved ones do not end when their service does. In many ways, it just begins,” the pair said.
“For many veterans, the hardest battles come long after they return home, and projects like this show them they have not been forgotten.”
Roberts-Smith is accused of murdering or ordering the murders of five unarmed detainees while deployed in Afghanistan between 2009 and 2012.
He has categorically denied the war crime allegations and remains on bail. He missed an expected appearance at the National War Memorial due to “illness” on Tuesday.
It comes after Ms Rinehart told the Bush Summit in Townsville said the veteran homelessness “really upset” her.
“Why isn’t Canberra listening? Are they so arrogant, are they so heartless, are they so unconcerned for their fellow citizens, their veterans, that they leaved closed their barracks doors and their other spare accommodation, and will not open this up for the approx. 6,000 homeless veterans that we have in our country,” she asked.
She also said the Townsville region could lean on billionaire Elon Musk for space-related infrastructure, or give land to Israeli defence specialists; and donated One Nation leader Pauline Hanson a model bulldozer as a symbol of red-tape reductions.
Earlier in April, the Hancock Prospecting boss pledged $200 million to tackle the homelessness issue.
The funding pledge is the largest ever private commitment for Australian war heroes.
Further buildings are expected to be acquired across the nation for the project.
Ms Rinehart confirmed a refurbished apartment block will open in July in South Perth.
Four further suitable acquisitions being actively sought in Queensland.
Ms Rinehart, named by Soldier On Australia as the “Honorary Guardian of Australian veterans”, has been a long-time backer of armed services personnel through generous support to Soldier On, the SAS Resources Fund, Commando Welfare Trust, Legacy and RSL.
