Federal cabinet minister Chris Bowen says there's no such thing as a safe seat anymore and he's going to fight hard for his.

Mr Bowen, who holds the western Sydney electorate of McMahon with a margin of around eight per cent, said Labor clearly had a challenge on its hands at the next election in September.

"Every politician (and) every member of parliament should go into every election campaign fighting hard for their seat," he told ABC television on Monday.

"There's no such thing as a safe seat anymore."

Mr Bowen acknowledged the Independent Commission Against Corruption investigation into alleged corruption by some former NSW Labor ministers in the previous state government had left some voters in the state feeling very let down.

"I do think that people have been ... disgusted with what they've seen at the ICAC hearings in NSW and they're right to be disgusted."

He nominated cost of living pressures, infrastructure and government funding for essential services like health and education as the main issues for western Sydney voters.
