The Australian government is due to release on Monday the final recommendations of the independent inquiry that exposed systemic wrongdoing in Australia's financial sector last year, likely leading to sweeping changes to the country's banking industry.

The big banks, insurers, pension funds and regulators who oversee the financial industry are bracing for a brutal summary of their misdeeds and weaknesses, and a list of tough recommendations including possible criminal charges.

The Royal Commission was a quasi-judicial independent body led by a former high court judge that was tasked by the government, reluctantly at first, with investigating financial sector misconduct following a string of banking scandals.
