1983, Minister for Aboriginal Affairs from 1981 to 1984, Minister for Youth and Community Services from 1983 to 1986, Minister for Housing from 1983 to 1988 and Minister for the Arts from 1986 to 1988. When the Unsworth government was defeated at the 1988 poll, he lost his seat. Federal political career Walker was elected as the member for Robertson in the Federal Parliament in 1990. He was Special Minister of State and Vice-President of the Executive Council from March 1993 to March 1994 and then Minister for Administrative Services until the defeat of the Keating government in 1996, when he also lost his seat. Walker's state and federal career both ended the same way that of him losing his seat at the same time that a sitting government, which he was a minister of, had been defeated. As a state minister, Walker's portfolios included Attorney General and Aboriginal Affairs and while he did not serve in these two portfolios as a federal minister he did however revisit these portfolio areas. This was due to the High Court's ruling on Mabo falling under his purview as Special Minister of State. On September 8, 1993, Peter Reith was appointed Shadow Special Minister of State and therefore Walker's Opposition counterpart. Reith was a member of Shadow Cabinet but Walker in contrast was a minister in the Outer Ministry and not a member of Cabinet. Walker criticised the appointment of Reith as his Opposition counterpart, specifically on Mabo. Walker said for Reith to deal with the rights of Aboriginal people was "as appropriate as appointing Saddam Hussein to look after the welfare of the Kurds". Walker described Reith as "a suburban solicitor" who got grappled with complexities of Mabo.

He was also president of the Schizophrenia Fellowship from 1998 until his death in 2012. His two sons, who had schizophrenia, both killed themselves when they were 33. Walker died of cancer, aged 69. His family accepted the offer of a state funeral that was held on
