Attorney-General Michaelia Cash says class action reforms and a federal integrity commission will have to wait until after the election as the government pursues laws on religious freedom and online trolls in the final days of parliament.

Senator Cash said the first priority of the Prime Minister was to ensure passage of the Religious Discrimination Act and to remove the right of faith-based educational institutions to expel gay students under section 38(3) of the Sex Discrimination Act. The next priority was to amend privacy laws to help combat online abuse.
