Replace the old income line first; otherwise every subscription, transfer and bill setting is being tested against money that may no longer arrive.

Replace the income line before trimming expenses
Start with net amounts actually paid for comparable periods, not the hours you hoped to receive. Fair Work Ombudsman says pay slips must show the pay period, payment date, gross and net amounts, and separately identifiable items such as loadings or allowances. Those fields help explain why two pays differ before you label the change permanent.
Moneysmart says a variable weekly income can be entered as an average and a budget should be updated when income changes. Use an average only across comparable periods: keep overtime, leave payouts or a partial first week visible rather than quietly blending them into a normal baseline.

Build an old-pay and current-pay baseline
Create two short rows: four ordinary pays before the hours changed and four current pays after the change. For each, copy the net amount and note the pay period, paid hours if shown, loadings, allowances and unusual adjustments. If the periods are not comparable, do not force them into one average.
A single low pay may reflect an unpaid day, payroll correction or different penalty-rate mix. A single high pay may include overtime. The purpose of the rows is not to decide an employment entitlement; it is to keep household recurring commitments tied to evidence you can reconcile with the pay slip.

Recalculate the recurring weekly load
Illustration only: four previous net pays of AUD 920, AUD 940, AUD 960 and AUD 960 total AUD 3,780, or AUD 945 a week. Four current pays of AUD 760, AUD 780, AUD 780 and AUD 760 total AUD 3,080, or AUD 770 a week. These invented amounts are not wages or award rates.
If recurring essentials and fixed transfers total AUD 610 a week, the amount left falls from AUD 945 − AUD 610 = AUD 335 to AUD 770 − AUD 610 = AUD 160, a weekly change of AUD 175. List each recurring debit beside its next date; do not treat the AUD 160 as spendable until irregular essentials and any arrears are also considered.

Test whether the change is temporary
If one week of extra shifts lifts pay again, keep the current recurring settings under review rather than immediately restoring every old transfer or subscription. If the lower pattern continues, update the budget with the new evidence and review each flexible commitment before its next debit date.
Moneysmart recommends comparing income and expenses and adjusting the budget as circumstances change. Your next step is to total four comparable current net pays and the next seven days of recurring commitments; that reveals the immediate gap without pretending to predict future rosters.
