[3] On 6 December 2017, shortly after the conclusion of the 2017 Women's Rugby League World Cup, which concluded with the Jillaroos defeating the New Zealand Ferns by 23–16 in the final,[4] it was announced by the National Rugby League that the inaugural NRL Women's season would operate in a round-robin format, and be held in August 2018, towards the back end of the men's season, with some matches to be played as curtain-raisers to NRL finals matches.

[11] Other clubs, such as the Melbourne Storm,[12] Manly Sea Eagles, Gold Coast Titans, North Queensland Cowboys, Canberra Raiders, Wests Tigers, Parramatta Eels, Penrith Panthers and Canterbury Bulldogs, all decided to delay bidding, citing money and time constraints.

[13] On 27 March 2018, the National Rugby League announced that the Brisbane Broncos, New Zealand Warriors, St. George Illawarra Dragons and Sydney Roosters had won bids to participate in the inaugural NRL Women's competition, commencing in September 2018.

[19] The clubs that made submissions for an NRLW licence in the expanded competition were: Canberra Raiders,[20][21] Cronulla Sharks,[22] North Queensland Cowboys,[23][24][25] South Sydney Rabbitohs,[26] Penrith Panthers and Wests Tigers.

In June 2022, the NRL changed their stance and decided to bring all expansion sides in together with the four teams all be admitted in the 2023 season[29] and that those four clubs were Canberra, Cronulla, North Queensland and Wests Tigers.

[30][31] Following the announcement both the South Sydney Rabbitohs and Penrith Panthers released statements congratulating the clubs that had been chosen and that they both would be interested in joining the competition in future seasons.

[32][33] The 2023 NRLW season ran for 11 weeks with 9 rounds, Semi-finals and a Grand Final with the Newcastle Knights claiming their second premiership and the first of the expanded 10 team competition.

On 28 March 2024, the NRL announced that the competition would expand by two teams in the 2025 season, with the addition of Canterbury Bulldogs and the return of the New Zealand Warriors.

[38] Prior to the commencement of the NRLW home-and-away season teams use this time to organise trial matches to test playing combinations.

[39] Due to measures in place to mitigate the COVID-19 pandemic in Australia in September-October 2021, the 2021 NRLW season was postponed until February 2022, with the Grand Final held as a stand-alone match on Sunday, 10 April 2022.

[41] This would be around one month after the Women's Grand Final and preseason tournament Auckland Nines in previous years was replaced.

In its inaugural season all matches will be televised live by affiliate partners the Nine Network and Fox League.
