PM faces the less friendly camera in its first week sitting

Prime Minister Scott Morrison is heading into his first week in parliament with diminished numbers in the  lower house.

After two weeks of preaching his values, Scott Morrison prepares for a baptism of fire in his first week in parliament as prime minister.

The coalition will no longer have a majority in the lower house and Labor must take full advantage of the fact.

With Malcolm Turnbull out of parliament but not replaced, and National Deputy Keith Hogan promising to move to the bench, the majority of the government with 76 seats was reduced to only 74.

The work is in 69 seats, with Emma Husar back after she was investigated for intimidating her staff.

There are five crossbenchers.

The figures mean that President Tony Smith can be required to vote with the government to break the stalemate in voting.

Opposition spokesman Andrew Leigh says Labor will use question time to ask why the Liberal Party felt the need to oust Mr. Turnbull.

"We still do not have a clear answer for that," he told ABC TV on Sunday.

He said that Labor will not allow the government to forget its decision to close the House of Representatives at the beginning of the last fortnight, or that some ministers publicly backed Turnbull before supporting his fall.

The Minister of Internal Affairs, Peter Dutton, said he is also prepared to defend his decisions on the visa during question time, as pressure grows on the revelations that he granted visas to European nannies in 2015.

Mr. Morrison's vice president, treasurer Josh Frydenberg, will not be by his side when the week begins.

Mr. Frydenberg will miss his first day of parliamentary session in the new position, since on September 10 he marks Rosh Hashana in the Jewish calendar.

He and his liberal parliamentary colleague Julian Leeser will be absent on Monday, along with Jewish Labor MPs Mark Dreyfus and Michael Danby.

In the Senate, the government has incontrovertible legislation that it is trying to pass, such as reforms to care for the elderly, since it seeks to minimize opportunities for Labor to cause problems.

In the lower house, changes in laws will be discussed to prevent victims of family violence from being interrogated in court by criminals.
