POLICE have charged four people after protesters stormed Kevin Rudd's Brisbane electorate office.

The protesters injured a member of the former prime minister's staff.

The sit-in protest was in response to the Prime Minister Julia Gillard's Closing the Gap speech in federal parliament earlier today.

Ms Gillard told parliament that efforts to close the life expectancy gap between indigenous and non-indigenous Australians would have to speed up to meet the official target by 2031.

The warning came as she delivered the fifth annual report card on efforts to close the gap on indigenous disadvantage.

There is a life expectancy gap of 11.5 years between indigenous and non-indigenous men and 9.7 years between women.

The protesters at Mr Rudd's office were calling for indigenous sovereignty to be recognised and for more consultation with indigenous communities on decisions affecting them.

Police told AAP that officers had been called to Morningside - where Mr Rudd's office is located - after reports of a disturbance.

A spokesman for Mr Rudd said 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, hurting her leg.

As a result a 50-year-old Marsden man has been charged with entering premises and committing an indictable offence, while two 62-year-old men from Camp Hill and a 35-year-old woman from Woolloongabba have been charged with trespassing.

All are due appear in the Brisbane Magistrates Court.
