Western Force star Courtney Hodder is among 26 of the 45 players to come from outside last year's World Cup squad.

Super W champions NSW had 16 players including Grace Hamilton who is tipped to replace the retired Ash Hewson, while Queensland has 11, WA 10, ACT six and two from Victoria.

Meanwhile, Queensland rising star Alysia Lefau-Fakaosilea missed out on a spot as she is not eligible for Australian duties until March next year, having moved from New Zealand.

Players will train in their state bases ahead of two Tests against the Black Ferns in August.
