The starting pay between audit and consulting is about the same, but long term prospects is heaven and earth.

The typical big 4 auditor path grad with 10 years exp is some kind of Finance Manager / Internal Audit in a big organization making 12-15k.

Those on consultancy side with same 10 years exp either move on to prestigious management consultancies, investment related fields or business strategy/M&A/JV specialist in a big organization. At this stage making above 25k is pretty common.
