They are pumping up a 4-game series between USA and Canada in Sydney, Melbourne, Brisbane and Perth in June. The games are all on Saturdays so there's no clash with their RL games. The NHL is all on FoxSports live and the AUS Ice Hockey league has no TV coverage that I am aware of.
It might not clash with Channel 9's RL coverage, but they're advertising the tickets. Presumably there might be people who buy tickets for those games who might have otherwise gone to a RL match. It's a minor thing I know, but it just strikes me as odd that in the middle of a RL match, they start talking up tickets for a different sport.
