The maximum basic rate for a single person is $834.40 per fortnight, and the maximum basic rate for a couple is $629 each per fortnight.
DSP levels taper according to income level, but if you earn over approx $2,000 per fortnight as a single person, or $3,000 per month for a couple living together, then you are unlikely to be eligible.
For every dollar of income over $172 (single person) or $304 (couple), the DSP reduces by 50c.
Please note that these figures may change. Visit the DSP payment rates page for updated information.
