New West Australian Labor MP Tania Lawrence has spoken of how her drive to enter politics was strengthened by watching the Morrison government's "betrayal of the Australian people".
In her first speech to the lower house on Thursday, Ms Lawrence - who was elected to the seat of Hasluck in May's election - said she was angered by the previous government who "did not care".
"I could no longer stand by and witness the abject betrayal of the Australian people," she said.
"The previous government made me angry and motivated me and my volunteers to work to make change."
Ms Lawrence spoke about the mandate given to the government by voters for an anti-corruption watchdog and affordable housing.
She also slammed the coalition for "recklessly creating divisions within our society and families" and "demeaning" people seeking support.
In her own debut speech, Liberal MP for the NSW seat of Hughes Jenny Ware quoted Ancient Greek philosopher Plato as she spoke about the rights of women and their entitlement to education and opportunity.
Ms Ware said as a mother of two boys she was conscious of being a role model for them, and teaching them to value and respect women.
The Sydney politician dismissed the idea the Labor party was the only option for women to join.
"It was our Liberal founder who specifically spoke about the need for women within the party and as members of parliament," she said.
"My role in rebuilding the Liberal Party will be in developing policy relevant to Australians, within the Liberal brand of a strong economy and a fair society."
Ms Ware noted home ownership in her electorate was increasingly becoming out of reach for ordinary people and committed to working to address cost of living pressures.
She also spoke of her support for action on climate change through empowering businesses and communities to take up clean technology.
