Assistant Treasurer and Financial Services Minister Stephen Jones will not recontest his NSW seat of Whitlam at the federal election, ending his 15-year parliamentary career.
In his final speech, Mr Jones thanked former prime minister Julia Gillard for her courage in setting up the royal commission into child sexual abuse.
"The royal commission was a really painful experience for survivors, but a necessary piece of truth-telling and reconciliation," he said on Tuesday as his voice trembled.
"Survivors, including me, appreciate it.
"A point I've never disclosed because I didn't want to be defined, and because I didn't want to detract attention from those who, unlike me, didn't have a voice, didn't have access to power to tell their story.
"There is power in being seen, being heard and being believed."
Despite joking he was now a "bit fatter, a bit greyer" from when he was first elected, Mr Jones also used his speech to highlight another concerning issue.
He said the nation could not be serious about taking on bigotry unless it stood up to online giants.
"We don't have a serious program to take on anti-Semitism and other forms of racism," he said.
"It's a matter of deep regret that we appear to be going backwards, and not forwards in that area."
He finished his speech by thanking the parliament for "the ride".
There were also farewells on Tuesday for former Liberal MP Kevin Andrews, who was remembered as "decent and duty-driven" by former colleagues from both sides of the political divide.
Mr Andrews, who held the Victorian seat of Menzies for three decades, died in December following a year-long battle with cancer.
His wife Margie listened on the floor of the House of Representatives as Australia's leaders paid tribute to her husband during Question Time on Tuesday.
Anthony Albanese said the former minister in the Howard and Abbott governments was marked by his "deep faith, belief in public service and devotion to his family".
"Kevin Andrews was regarded by his opponents with true respect and affection," the prime minister said.
"This was indeed a man determined to fill every page, his life was indeed a very full story.
"Our condolences to the Liberal Party of Australia, an organisation that he loved and served with loyalty and with distinction. May Kevin Andrews rest in eternal peace."
Opposition Leader Peter Dutton said the avid cyclist had revealed himself early in his career as a parliamentarian of "profound skill and a man of principle driven by his Catholic faith".
"Dignified, decent, determined and duty-driven," Mr Dutton said.
Addressing Ms Andrews, Mr Dutton said she and her husband had been a "formidable partnership".
"Together you created an amazing legacy for your family and for this country. And we pay our respects, our deep respects, to you and to your family.Â
"May God bless Kevin Andrews, and may he rest in peace."
