What's with the Unemployment Benefit?

New Social Development Minister Ruth Dyson says that only 20,000 are now on the unemployment benefit. The September Household Labour Force survey says there are 79,000 unemployed. Now I know they are different measures but in Australia the two roughly tally.

In September 2005 the HLFS had exactly the same number unemployed - 79,000 - as September 2007, but then there were 50,000 on the unemployment benefit. Now there are 20,000.
