Australia's Prime Minister Scott Morrison has declared his home affairs minister safe despite an inquiry finding that he misled parliament.

A Senate inquiry on Wednesday recommended that Home Affairs Minister Peter Dutton should be censured after finding that personal relationships influenced his decision to release two au pairs from detention and grant them visas.

The opposition Australian Labor Party (ALP) used the inquiry's findings to call for Dutton's sacking but Morrison on Thursday said there was no need.

"The Labor Party's about stopping au pairs. We're about stopping boats, criminals, bikie gangs," Morrison said.

Dutton intervened in June 2015 when a former colleague from the Queensland police force contacted the minister's office requesting help for an Italian au pair who was detained at Brisbane airport.

Five months later he intervened again when Gillon McLachlan, chief executive of the biggest sport league in Australia, the Australian Football League (AFL), made contact on behalf of his second cousin when a French au pair was detained at Adelaide airport.

Dutton told parliament in March that he did not have any personal relationship with "the intended employer of either of the au pairs."

"It is the view of the committee that Minister Dutton had a clear personal connection and existing relationship with the intended employer of the au pair in the Brisbane case," the inquiry's report said.

"Given his definitive answer in the House of Representatives, it is the view of the committee the Minister misled parliament in relation to this matter."

Adam Bandt, a Member of Parliament for the Australian Greens, on Thursday moved a motion of no confidence against Dutton to force his resignation but it was defeated by the government.

"In respect to the minister for home affairs you can not trust what he says," Bandt said.
