All my toons were level 80 when I started, and I haven't leveled a fresh alt yet, but what is the minimum level for cataclysm content? I assumed it was 2 levels under cap like the other expansions, and on the cataclysm EU site, Hyjal is advertised as the "all-new level 78-82 zone will feature..."
Question being, what level does she actually have to be to start in Hyjal or Vashj'ir?
They lowered the amount of exp needed for 71-80, so it shouldn't be that much of a headache getting 2 more lvls. I personally quested in Zul'Drak while queueing for dungeons, and got from 71-80 in about 3 days or so, playing casually. Keep on truckin
The requirement is 80, but my fresh holy pally dinged 80 right on cata release so I was still in wrath blues/greens. It may have just been from me leveling as shockadin but hitting new content in that sort of gear as that spec was a bit rough. So you may want to help her get started and just let her know that it will be rough starting out ( depending what you are playing i suppose ).
