To watch the NWSL in Australia, Twitch seems to be the only channel unless they upload the games to the NWSL app once they've been broadcast.
The following sites should provide some coverage and commentary of the Challenge Cup. I've listed the Instagram accounts but they all have Twitter and Facebook pages as well.
Molly's Footy Rants @mollysfootyrants Independent pundit giving interesting and original commentary on all women's leagues across the world. Will be providing opinions on the Cup worth reading. Definitely worth following. W-League @wleague Always covers the NWSL but especially from the view of players that have played in the W League, which is a large number of NWSL players. They should show some highlight packages and especially goals scored by W League players. Matildas @Matildas Covers the Matildas only but for their clubs as well as the national team. The Women's Game @thewomensgame Covers a range of Australian women's sports including AFLW, Cricket, tennis, athletics and basketball but biggest focus is on football. Optus Sports @optussport
Covers football with a focus on the Premier League but also covers the WSL and the Matildas. They may provide some coverage of the Challenge Cup but they may not.
