The best thing about SBS is that everything is streamed online live, regardless of TV schedules. Nine will not be so accommodating, which means back to three hour additional delay here in the West
The coverage should be dictated by the operator of the event. I think I'm correct in saying that they equipment and personnel for the TV coverage, and from there sell those rights (this is the only way you can get small cycling events covered). So if the organisers decided they want all stages covered properly ("live") then that will happen. They are saving themselves a million or so in 2012 year so why don't they put it into the coverage, rather than continuing to pretend the race is anything other than Mickey Mouse. Phil and Paul like to call it the 3rd best race in the world (maybe 4th now after USPCCCCCC), amazing that the 3rd best race only has two stages televised, and even then to a very limited audience.
A deal with Nine would obviously be about money. Again, if they cared about the race they would have it written in the deal that "live" must actually be live, across the country. They must do this, in the best interests of the race. Maybe the political situation means the government are trying to scale back their financial commitment. The race isn't going to make money, but maybe they can minimise their exposure.
I get the picture that the overseas coverage is limited. Highlights shown long after the completion of the race, and I'm not even sure if the live stages were shown. This is understandable in some respects due to the season not having started in the Northern Hemisphere, and the time of day in which the race is on. This should be improved, especially as the event is considered an exercise in tourism.
So, what I think the race needs (on this front):
1) Live coverage of all stages.
2) Domestically, guarantee with the rights holder that the race be broadcast live.
3) Internationally, negotiate with broadcasters to see if they are interested in increasing their coverage. An easy part of this would be to get a deal with Eurosport which gives you some sort of audience in several countries across the continent.
As a side note, Nine cannot be trusted to do anything without actually putting it in the contract, given their "coverage" of the RWC.
