Given that we don't have a media that will hand out press coverage for us we need to really work hard for all our publicity. We can't sit back and hope that things improve, we need to get out there and make it happen. For starters, I would organise a national tour of the country, focused on areas where the games are occurring and taking the trophy to local schools, fetes, shows etc to generate publicity in the local area. We could perhaps work with logistics partners to facilitate this e.g. a car hire company to transport the stands, trophy etc between towns.
I would also try and engage with the national network of Rugby League clubs by offering them incentives to buy tickets (such as cashback schemes) as this effectively gets the clubs working as sales agents for the World Cup.
Finally, given that we are not blessed with a massive budget for the tournament, I would seek to make use of social media by creating profiles on Twitter, Facebook etc and then holding competitions and posting regular updates to engage with the millions who use these channels.
I would like to see the TV broadcaster of the major games (BBC) promote it more. Not just on TV but also on web-sites in particular BBC sports website. For example like Sky did for the recent Lions tour. When ever I clicked in to watch a Rugby League video on the Sky website I got a promotional advert about the Lions tour before the video sequence.
Through the clubs community, school work, and other RL web sites could have competitions for the children that included having to get parents participation. If at the beginning did a really big prize (a bit like willy wonka golden ticket) through web sites and social media of RFL, clubs and Broadcaster that built up week by week that reached a crescendo with the grand prize.... Hospitality for them and family plus on air seat in the BBC commentary panel for major match days and trips to NRL games in Australia, etc etc...
