On 2 December 2015, in the 44^th Parliament, the committee commenced an inquiry into the integrity of Australia's border arrangements. The inquiry was re-referred at the beginning of the 45^th Parliament, and lapsed with the dissolution of the House of Representatives on 11 April 2019.

Information on the inquiry in the 44^th Parliament is available here, and in the 45^th Parliament here.

On 24 July 2019, the committee resolved to re-refer the inquiry in the 46^th Parliament, and to refer as it sees fit to evidence to the inquiry received in the 44^th and 45^th Parliaments. This means that submissions already provided to the committee for this inquiry do not need to be resubmitted.
