There is next to nothing in the british media regarding the upcoming Roo tour. I think there are a few factors that attribute to this:
1. Football (Soccer) represents 90% of the sports pages in the papers. And this doesnt look to be changing anytime soon.
2. The Rugby world cup
3. GB havent won the thing in 30 odd years, and I guess the media have lost interest (cant really blame them)
Yes, I do believe that If the poms got up it would help league in the UK, however it would only be a mear few days before Soccer and Rugby flooded the papers again.
