Yes, the word order is fine. And there is nothing incorrect about the sentence.
Mass media representatives will be present [at the conference].
They will be there for the official coverage of the course of the conference. They will be there to cover it in some official capacity.
The course of the conference refers to whatever transpires during the conference.
And yes, there are other ways to say the same thing or similar. But you asked about this sentence (dunno whether it is yours or one you read somewhere). If you really meant to ask about writing alternatives to such a sentence, say so. Other answers here seem to be trying to help with that. But this sentence is fine as is.
