The vernal equinox, and the autumnal equinox, happen in a single moment for the entire globe; they are not on-going phenomena that start at one time and end at a later time. The vernal equinox (in the north) will be March 20 2013 at 11:02 UT, which is for all practical purposes the same as 11:02AM, Greenwich Mean Time. This is the autumnal equinox in the Southern Hemisphere.
Each year the actual time of the equinox changes by several hours, a table showing all forthcoming times and dates can be found on the related link.

Does the autumnal equinox mark the beginning of fall for both hemispheres?
That is depending on what you regard as the autumnal equinox. The autumnal equinox in the northern hemisphere is in September and it marks the start of autumn. In the southern hemisphere the autumnal equinox is in March and it marks the start of autumn. So looking at in that way, you can say yes. Of course those are two different dates on the calendar, so the autumnal equinox in one is happening at the same time as the spring equinox in the other. It is the same equinox, but where on Earth you are, determines which equinox it is. As autumn starts in one hemisphere, spring is starting in the other. So on that basis they don't mark the start of autumn in both hemispheres. It is never the same season in both hemispheres.
