Report
AI Summary
This report details a forensic accounting investigation into potential betting fraud within the Australian Football League (AFL). As part of a graduate placement with Victoria Police, the investigation focuses on scrutinizing data files recovered from the laptop of an accused ringleader, comparing this data against official AFL records from 1897 to 2017 to identify instances of data manipulation. The report outlines the process used, including data collection, merging, sorting, and the application of Excel's "IF" function to highlight discrepancies in match scores. Five specific examples of altered data are presented, revealing a pattern of betting fraud since 1992. The findings suggest that the risk of betting fraud in the AFL is more extensive than initially suspected, necessitating further precautions to protect the integrity of the league's results. This document is intended to show examples of how data analysis and forensic accounting techniques can be used to detect fraud.

Introduction:
Despite development of number of advanced accounting tools including customized
software the popularity of excel spreadsheet is yet undiminished. In fact the use of spreadsheet is
present in across the globe and experts prefer using spreadsheet to conduct data analysis. In this
document the data of Australian Football League (AFL) matches since 1897 have been analysed
by using different useful functions of excel spreadsheet to make certain assertions in regards to
these data. The matches played from 1897 till 2018 are to be investigated for possible risk
betting fraud. Considering the huge size of total number of data effective use of excel
spreadsheet would be immensely beneficial to identify changes in the data of these matches
(Abers and Hacker, 2016).
5 specific examples of data changes identified in excel spreadsheet:
Using certain important functions of excel, number of matches have been identified
where data has been changed in the file of the betting ringleader from the original data. Out of
those matches here are five such matches of AFL where data has been changed.

above five examples show how the betting fraud is a reality as is visible in the above example
table.
Process used to identify the above examples:
The step by step process used to conduct the investigation on AFL matches are provided
below:
Data collection:
At the very beginning, the original data of AFL matches were collected from the official website
of AFL. The data of each matches since 1897 in chronological order was exported in an excel
file. Also the file recovered from the laptop of arrested betting man was kept in right condition as
it was recovered without any changes (Christensen and Schneider, 2017).
Merging of data in a single file:
The original data of AFL matches were merged with the data maintained in the arrested betting
man’s laptop. In order to merge the data firstly an additional column each was inserted right

beside the score column in betting man’s file. One column each was inserted for team 1 score
and team 2 score.
The following image would be helpful in understanding the process used to merge the data:
F and G columns and J and K columns were inserted in the betting man’s file to conduct data
analysis on the AFL matches (Steinbach et. al. 2015).
Sorting and filtering:
After insertion of separate columns as shown in the above image, sort and filter function of excel
were used to sort and filter data according to requirements of the investigator. The image below
depicts where the sort and filter function is located and how to use the function (McFedries,
2016)
This function helped in sorting and filtering data on the basis of date, team 1, team 2, score and
venues. Thus, as per the requirement of the investigator data can be sorted and filtered using any
or more of the above data classifications.

“IF” function and use for identification of games where data has been changed:
“IF” function is an important function of excel spreadsheet which helps in conducting data
analysis on the basis of certain logic. In this case the logic has been based on the score of the
AFL matches (Conant, 2018). The formula has been created in such a way to compare the scores
of AFL matches as recorded in betting man’s file with the original scores of these matches. The
following image shows the formula that has been used to compare the data of AFL matches.
As a result, in case the data in betting man’s file has been changed will be highlighted by FALSE
where as TRUE sign will indicate no changes in data. The screen shots below taken from the
excel file where the analysis has been conducted would help in identifying the matches where
data has not been changed (Li et. al. 2017).

Finding:
Finding from the investigation clearly indicates that there are number of matches in AFL
since 1992 where data has been changed for betting purposes. Here only five instances of such
matches have been provided where data has been changed however, the number of matches
where data has been changed is huge (Harkins, 2016).
Observation of the finding:
It is frightening to conclude that the betting fraud risk in AFL is much worse than
primarily suspected. The betting has been continuing since 1992 and is very much a part of the
annual sporting league even at the present. The examples have been specifically given to clearly
show that the betting has been in force since 1992 and is continuing even in the present. The
table below shows that from 1992 till now in 2018, the changes have been made to the original
score in the betting man’s file to manipulate the records for betting purposes.

From the above it is clear that the risk of betting fraud is much worse than primarily suspected at
the beginning. This is not about one or two matches but a whole host of games of AFL where
unauthorized changes have been made to the original score as per the manipulative file recovered
from the excel file of the betting man. Thus, all necessary precautions shall be taken to ensure
there is no way betting fraud can impact the results of the AFL matches (Harris et. al. 2016).
