Proposed laws to establish a long-awaited national, independent anti-corruption watchdog have been introduced to parliament.
Attorney-General Mark Dreyfus introduced legislation to the lower house on Wednesday to set up the integrity commission, which will cost $262 million over four years and $90 million more than an earlier coalition proposal.
He said the body - to be known as the National Anti-Corruption Commission - would operate independently of the government and have powers to investigate serious or systemic corrupt conduct across the commonwealth public sector.
