Colleagues
Below is an update on the cumulative outcomes from the sampling activity up to
3.00pm 30 August 2023.
562 debts have been reviewed in total
§ The average time for the investigation component: 1hr 09mins (staff
declared timings)
§ The average time for the recalculation component: 3hrs 41mins (staff
declared timings)
- We anticipate this time will increase, as there are 47 recalculations
outstanding
132 of the 562 undetermined debts reviewed so far are not related to
employment income, which demonstrates our data limitations and why
manual checking of records is required
Of the 430 undetermined debts related to employment income, 77% were
impacted by income apportionment:
§ 333 were income apportioned
§ 63 have sufficient evidence available on the record to conduct a
recalculation (which remains a lower proportion than we had
expected)
§ 16 recalculations have been completed:
- 9 resulted in a downward variation – averaging of $351.70 (16.4%),
highest reduction was $1,498.05
- 7 resulted in an upward variation – averaging of $7,159.25 (61.7%),
highest increase was $25,779.41
Note: There are 2 recalculations that are showing as significantly
higher than the estimated ADEX debt amount. This is due to the
estimated ADEX debt amount only covering a portion of the debt
period. We now have a process to determine the estimated debt
value for the full period, to allow an accurate comparison. These
updates will be provided in tomorrow’s report.
- The longest calculation took 8hrs 20mins

Income Apportionment | Sampling Outcomes 25.08.23 (Cumulative) [SEC=OFFICIAL]
Date:
Friday, 25 August 2023 6:00:41 PM
Colleagues,
 
Below is an update on cumulative outcomes from the sampling activity up to 3.30pm
25 August 2023.
 
265 debts have been reviewed in total – average of 4.3 per staff member per
day
Average time for the investigation component:  1hr 29 minutes (staff declared
timings)
73 of the 265 undetermined debts reviewed so far are not related to
employment income, which demonstrates our data limitations and why manual
checking of records is required
Of the 192 undetermined debts related to employment income, 75% were
impacted by income apportionment:
§  144 were income apportioned
§  45 have sufficient evidence available on the record to conduct a
recalculation (which is a lower proportion than we had expected)
§  1 recalculation has been completed (due to the focus on triaging), which
took 5 hours to complete:
-          resulted in a downward variation of $116.06
-          original undetermined debt = $193.47
-          recalculated debt using date paid method = $77.41
Staff have ‘triaged’ their initial allocation, and have commenced recalculations
via Multical today.  We anticipate additional recalculation outcomes early next
week.
Regards,
 
Chris

RE: Income Apportionment | Sampling Outcomes 29.08.23 (Cumulative) [SEC=OFFICIAL]
Date:
Tuesday, 29 August 2023 5:58:10 PM
Colleagues,
Below is an update on cumulative outcomes from the sampling activity up to 3.00pm
29 August 2023.
395 debts have been reviewed in total
§ The average time for the investigation component: 1hr 11mins (staff
declared timings)
§ The average time for the recalculation component: 3hrs 15mins (staff
declared timings)
98 of the 395 undetermined debts reviewed so far are not related to
employment income
Of the 297 undetermined debts related to employment income, 77% were
impacted by income apportionment:
§ 229 were income apportioned
§ 58 have sufficient evidence available on the record to conduct a
recalculation
§ 15 recalculations have been completed:
- 8 resulted in a downward variation – average of $383.80 (24.2%),
highest reduction was $1,498.05
- 7 resulted in an upward variation – average of $7,159.25 (61.7%),
highest increase was $25,779.41
Note: There are 2 recalculations that are showing as significantly
higher than the estimated ADEX debt amount. This is likely due to the
estimated ADEX debt amount only covering a portion of the debt
period. These will be reviewed tomorrow and outcomes updated (if
required).
- The longest calculation took 8hrs 20mins
· 11 additional staff were on-boarded and commenced sampling activity from
11am today.
· We are seeking to increase the efficiency of recalculations by allowing staff to
save these recalculations on the customer record overnight, so that rework is
not required. We have a treatment in place to mitigate the associated risk,
which even untreated is a very low risk.
· Where the sampling work finds issues requiring priority remediation, these
matters are being flagged for action once the sampling of these 1,000 records
is completed.

Chris

Income Apportionment | Sampling Outcomes 07.09.23 (Cumulative) [SEC=OFFICIAL]
Date:
Monday, 11 September 2023 7:01:24 PM
Colleagues,
As a result of discussions last week (thanks, Robert, for covering for me) in relation to
the second phase of the sampling exercise, we are proposing to undertake the next
phase in two tranches:
1.  AAT and formal reviews – using the same sampling process as we did over the
previous two weeks, however, drawing from AAT and formal review matters where
there has been an Explanation of Decision recorded, which we expect to increase
the likelihood of more recent customer engagement, and the probability that a
recalculation can be actioned; and
2.  Current apportionment matters with known debt recalculations – such as CDPP
matters (~47), and priority formal reviews (~215). We will extract and check the
relevant data on the same basis as the previous sampling so that it is a ‘like for like’
comparison. We expect this work to be able to be done more quickly compared to
the sampling work over the last fortnight, or even the AAT and formal review
referred to above.
With this new approach, we currently have a higher confidence that it will yield
approximately 150 – 200 recalculations by 22 September 2023.
We commenced this approach from 11.30am today, and results so far include:
17 records have been reviewed
These cases were from the priority review cohort where the recalculation had
already been completed
All cases were related to employment income
13 (76.4%) were impacted by income apportionment
13 had sufficient evidence to recalculate:
13 completed
11 resulted in a downward variation – averaging $1,029.56 (% changes will be
included in the next report)
2 resulted in an upward variation – averaging $802.13 (% changes will be
included in the next report).
Additionally, to improve the quality and accuracy of the daily sampling reports, we are
moving from an end of day to beginning of day reporting cycle (commencing from 13
September 2023). This will allow time to complete the quality assurance prior to
compiling the report, which will reduce the rate of revision of the previous day’s data.
Changes will include:
sampling data being collated at noon each day;
quality assurance will then be undertaken on the data; and
the daily sampling report will be compiled and distributed the following morning.
In relation to the first phase of the sampling process, below is an update on
cumulative outcomes up to 2.00pm 11 September 2023:
1,000 debts have been reviewed in total
807 were related to employment income, of these:

637 (+2) were income apportioned
67 (-1) have sufficient evidence available on the record to conduct a
recalculation (which remains a lower proportion than we had expected). 
The high level basis for the calculations is as follows:
11 - Daily rate – daily earnings method which calculates the debt
using the exact days and daily amounts paid in the relevant
Centrelink Entitlement period
49 - Received method – date paid method which calculates the
debt using the total income paid in the relevant Centrelink
Entitlement period
5 - Hybrid – a mixture of daily earnings and date paid methods;
could also include the use of bank statements to confirm date paid
Note: a recalculation is only conducted where there is evidence
available for the full debt period. Where any information is missing,
it is deemed insufficient evidence is available.
65 recalculations have been completed:
37 resulted in a downward variation – averaging $1,234.87 (or
12.4% of the debt value), highest reduction was $5,550.88 –
average duration of debt period is 740 days. Note: debts occurred
within this period, but not necessarily across the whole period.
27 resulted in an upward variation – averaging $1,299.64 (or 30.5%
of the debt value), highest increase was $5,026.74 – average
duration of debt period is 608 days. Note: debts occurred within this
period, but not necessarily across the whole period.
1 resulted in a NIL change
The average time for the investigation component: 1hr 33mins (staff declared
timings)
The average time for the recalculation component: 4hrs 24mins (staff declared
timings)
Longest time taken: 12hrs 50mins
Estimated Completion (subject to ongoing analysis):
Final analysis of outcomes for both phases, quality assurance and the final
report are expected to be finalised by 29 September 2023.
Regards,
Chris

The data below is the cumulative data from the first 1,000 undetermined debts
(Phase 1), and the second sample batch of 1,000 undetermined debts that we are
now progressing, and the recalculations (Phase 2).
The second sample of 1,000 undetermined debts has been drawn from the same
backlog of earned income cohort, and in the same way as the first 1,000. This
involves taking a mix of 100 for each of the ten years prior to 2020 by payment types.

Below is an update on the cumulative outcomes from the sampling activity up to
2.00pm 8 September 2023.
1,000 debts have been reviewed in total
§ The average time for the investigation component: 1hr 45mins (staff
declared timings)
§ The average time for the recalculation component: 4hrs 22mins (staff
declared timings)
194 of the 1,000 undetermined debts reviewed are not related to
employment income, which demonstrates our data limitations and why
manual checking of records is required
Of the 806 undetermined debts related to employment income, 78.8% were
impacted by income apportionment:
§ 635 were income apportioned – this has reduced from yesterday’s report
due to QA activity
§ 68 have sufficient evidence available on the record to conduct a
recalculation (which remains a lower proportion than we had
expected)
The high level basis for the calculations is as follows:
- 10 - Daily rate – daily earnings method which calculates the debt
using the exact days and daily amounts paid in the relevant
Centrelink Entitlement period
- 49 - Received method – date paid method which calculates the debt
using the total income paid in the relevant Centrelink Entitlement
period
- 5 - Hybrid – a mixture of daily earnings and date paid methods;
could also include the use of bank statements to confirm date
paid
- Note: a recalculation is only conducted where there is evidence
available for the full debt period. Where any information is
missing, it is deemed insufficient evidence is available.
§ 64 recalculations have been completed:
- 38 resulted in a downward variation – averaging $1,085.20 (or 10.9%
of the debt value), highest reduction was $5,411.93 – average
duration of debt period is 742 days. Note: debts occurred within
this period, but not necessarily across the whole period.
- 26 resulted in an upward variation – averaging $1,391.48 (or 40.1% of
the debt value), highest increase was $5,026.74 – average
duration of debt period is 571 days. Note: debts occurred within
this period, but not necessarily across the whole period.
- The longest calculation took 12hrs 50mins. This time has reduced
from 16 hours as QA has determined there was insufficient
evidence for a recalculation. The time taken for this recalculation
has been incorporated into the investigation timings.
We anticipate the remaining 4 recalculations will be completed on Monday
11 September.

The data below is the cumulative data from the first 1,000 undetermined debts
(Phase 1), the second sample batch of 1,000 undetermined debts that we are
now progressing (Phase 2) and a sample of recalculations.
The second sample of 1,000 undetermined debts has been drawn from the same
backlog of earned income cohort, and in the same way as the first 1,000. This
involves taking a mix of 100 for each of the ten years prior to 2020 by payment

Below is an update on the cumulative outcomes from the sampling activity up to
12.00pm on 22 September 2023.
The data below is the cumulative data from the first 1,000 undetermined debts
(Phase 1), the second sample batch of 1,000 undetermined debts (Phase 2) that
we are now progressing, and a sample of recalculations.
The second sample of 1,000 undetermined debts has been drawn from the same
backlog of earned income cohort, and in the same way as the first 1,000. This
involves taking a mix of 100 for each of the ten years prior to 2020 by payment

Below is an update on the cumulative outcomes from the sampling activity up to
12.00pm on 27 September 2023.
The data below is the cumulative data from the first 1,000 undetermined debts
(Phase 1), the second sample batch of 1,000 undetermined debts (Phase 2) that
we are now progressing, and a sample of recalculations.
The second sample of 1,000 undetermined debts has been drawn from the same
backlog of earned income cohort, and in the same way as the first 1,000. This
involves taking a mix of 100 for each of the ten years prior to 2020 by payment
types.
2,198 cases have been reviewed in total. However, 48 cases that do not meet
the scope of the sampling activity (debt start date post 7 December 2020) have
been removed. This has impacted the numbers outlined below. These cases are
undergoing further investigation.
Phase 1
1,000 debts have been reviewed in total
29 related to post-CAM income updates and have been removed from the

Recalculations
We have progressed a review of previously recalculated priority formal reviews
and CDPP matters.
Note: Following QA checks, a number of outcomes have been removed from the
report due to cases not falling within the scope of the sampling activity. This is
primarily due to debt ID’s being reduced to zero (and amalgamated into another
debt ID) and appeals being withdrawn without a recalculation being completed.
203 debts have been reviewed in total (2 cases were removed post QA as
they did not meet the scope of sampling activity. This has only adjusted
the % of debts related to income apportionment, the outcomes remain
unchanged.)
· Of the 197 debts related to employment income:

The data below is the cumulative data from the first 1,000 undetermined debts
(Phase 1), the second sample batch of 1,000 undetermined debts (Phase 2) that
we are now progressing, and a sample of recalculations.
The second sample of 1,000 undetermined debts has been drawn from the same
backlog of earned income cohort, and in the same way as the first 1,000. This
involves taking a mix of 100 for each of the ten years prior to 2020 by payment
types.
2,202 cases have been reviewed in total, however 48 cases that do not meet the
scope of the sampling activity (debt start date post 7 December 2020) have been
removed, which has impacted the numbers outlined below.
