Controversial NSW One Nation leader Mark Latham and Animal Justice Party vegan bodybuilder Emma Hurst will join other new MPs at Macquarie Street for the first sitting of the 57th state parliament.

More than six weeks after Gladys Berejiklian became the first woman to be popularly elected NSW premier, the coalition on Tuesday will return to the government benches.

Ms Berejiklian has a majority in the lower house but will have to deal with a rabble of crossbenchers in the Legislative Council including Mr Latham and fellow One Nation MP Rod Roberts.

They're joined by three Greens members, two MPs from the Shooters, Fishers and Farmers Party, two Animal Justice MPs - including Ms Hurst - independent Justin Field and Christian Democrat Fred Nile.

The new-look upper house comprises 17 coalition MPs, 14 Labor MPs and an 11-member crossbench.

Labor will try to take advantage of the government's weak position in the Legislative Council by teaming up with a handful of crossbench members to block legislation or force parliamentary reform.

The Shooters have three lower house MPs too, having wrestled two additional seats from the Nationals at the March 23 election.

They're joined in the Legislative Assembly by three independents: Wagga Wagga's Joe McGirr, Sydney's Alex Greenwich and Lake Macquarie's Greg Piper.

Ms Berejiklian has promised to focus on education and social inequality this term after years of government spending on roads, railways and stadiums.

She told the first meeting of her cabinet in April she hoped to break the cycle of intergenerational disadvantage.

Meanwhile Labor will return to parliament without a permanent leader, after Michael Daley stepped down following the election loss.

Upper house MP Penny Sharpe is Labor's interim leader with the leadership ballot process expected to begin after the May 18 federal election.

Kogarah MP Chris Minns is the favourite for the top job despite simmering tension between him and NSW Labor head office.
