Passing cap-and-trade in Australia

Australia has a big vote on cap-and-trade coming up; familiarly, attention is on exactly which compromises are required to bring on the necessary marginal voters:

Opposition leader Malcolm Turnbull has offered to deliver enough conservative votes to pass the legislation, but only if the government agrees to certain conditions. Among other things, he and others want emissions from coal mining and agriculture to be excluded from the proposal. They also have called on the government to delay the design of the Australian carbon program until February or March, after the U.S. Senate has debated its climate bill.

Umm... given that Australia gets 80% of its electricity from coal, that sounds like a dealbreaker.
