The Senate Community Affairs committee is calling for public submissions to its new inquiry into the My Health Record, with the committee due to report by October 8.

The inquiry was referred by Labor and the Greens to the committee to look into the government's handling of the roll-out, including the public information campaign and the decision to shift from an opt-in system to opt-out.

The latter was a matter for the committee's previous inquiry in October 2015, when it recommended the shift go ahead.
