Prime Minister Julia Gillard has delivered the fifth annual report card to Parliament on efforts to close the gap on disadvantages suffered by indigenous people.
The prime minister told parliament efforts to close the life expectancy gap between indigenous and non-indigenous Australians would have to gather pace to meet the official target by 2031.
There is a life expectancy gap of 11.5 years between indigenous and non-indigenous men and 9.7 years between women.
The Northern Territory is the only jurisdiction on track to meet the indigenous life expectancy equality target by 2030.
'The gap that separates our opportunity and living standards must be closed,' Ms Gillard told parliament.
'Already we know that some targets like life expectancy will be enormously challenging to meet, even with almost two decades still to run.'
Meanwhile police are speaking to four people after protesters forced their way into Kevin Rudd's Brisbane electorate office, injuring a member of the former prime minister's staff.
The sit-in protest was in response to the Ms Gillard's closing the gap speech in federal parliament.
The protesters were calling for indigenous sovereignty to be recognised and more consultation with indigenous communities on decisions affecting them.
Police told AAP officers had been called to an address at Morningside - where Mr Rudd's office is located - after reports of a disturbance.
No charges have been laid and police say four people are assisting them with their inquiries.
A spokesman for Mr Rudd says a small group of protesters forced their way into the private area of the office when a staff member opened a security door to let a guest out.
The staffer fell and hurt her leg.
'Other staff and volunteers in the office at the time are understandably shaken,' he told The Courier Mail.
'At this stage the protesters have not offered an apology to the staff members present at the incident.
'Mr Rudd thanks the Queensland and Federal police for their fast and professional conduct.'
