Australia's youngest senator has vowed to be a tireless champion for people with disability, urging politicians to do more for future generations.
West Australian Greens senator Jordon Steele-John made his first speech to parliament on Wednesday after being sworn-in earlier in the month as the replacement for Scott Ludlam - the first MP to leave parliament over the dual citizenship saga.
Senator Steele-John, 23, who has mild cerebral palsy and uses a wheelchair, said his presence in parliament was a radical departure from the norm.
"It is very clear to anybody who takes the time to look that the Australian people are no longer satisfied with what they are getting from their politics," Senator Steele-John said.
"They will not cop politics-as-usual any longer."
Senator Steele-John asked his followers on social media: "If you could say anything to the people in this place, what would you say?"
Indigenous rights, action on climate change, housing prices, refugees on Manus Island and big corporations not paying their fair share of tax topped the list of concerns.
There was also some lighter advice for the government.
"My favourite so far has been the suggestion the government might perhaps try turning itself off and back on again - that was the cleanest one we could find," Senator Steele-John said.
He said there was a need to address society's collective failure to adapt to and celebrate people's differing levels of ability.
"I will be a tireless champion for the way society thinks about people with a disability," Senator Steele-John said.
The English-born senator - who has renounced his British citizenship - said if parliament continued failing to deliver, more people would turn away from politics.
"The challenges before us now are profound. But I sit here tonight brimming with the belief that we can and will meet those challenges together," he said.
