My Niece has Binge, my Mum has foxtel, but we have tried Kayo doesn't come with Binge, it's seperate
Sweet. In that case if your mum is cool with it, you can use her Foxtel account and use Foxtel Go to watch the NRL.
That's how we do it here (using my parents Foxtel account).
I have 2 small computers hooked up to our home theatre and master bedroom TV's and connected to TVs, that's how we use all streaming platforms.
Works an absolute treat and plenty good enough to watch.
If you have internet with Telstra Bigpond, it doesn't count in your data usage either
