Titans are moving rapidly into PNG.
The problems that I see with those locations(papua, fiji, are the grounds, broadcast, travel & time zones.
Broadcast units could be custom built to suit in a container, then transported complete. Those units could then service all pac rim islands & papua for years.
Fiji, vanauatu, Samoa, Tonga, solomons etc etc.
The time zone would work for the Saturday 5.30 game live for pac rims or 7.30 live for papua.
The cost of accommodating the broadcast unit is negligible & the Sharks or NRL would have to come to the party for the difference in travel costs for the opposition I guess.
It can be done.
