They may be large. The Great Artesian Basin aquifer covers about 1.7x106 km2. This aquifer may underlie more than 20% of the Australian continent. It is very important for agriculture and pastoralism, and is nationally managed.
In 2009 fracking for Coal Seam Gas introduced noxious chemicals into a Queensland portion of the acquifer, and this is not regarded lightly.
There are major and important aquifers on all the continents.
[Lake Vostok in the Antarctic lies under >3000m of ice, but its surface is about 500m below sea level. Of course, if the ice were removed, the isostatic rebound of the landmass may rise the lake above sea level. But true aquifers will be in that continent.]
