Tax question - medicare levy

So i just got my notice of assessment.

At the bottom it says Your Medicare levy surcharge, included in Medicare levy and surcharges, is $1,015.05 which is 1.00% of your income for Medicare levy surcharge purposes.

However in the actual calculations Medicare levy and surcharges is listed as 3,045.15 - which is 3x this amount.

Can someone explain the discrepancy?
