Forensic Accountant for Underpayment Spreadsheet

I need an expert Australian forensic accountant to build a 100% accurate underpayment spreadsheet for a federal court claim. Case Details: Period: 07/11/2022 to 19/12/2025 (approx. 8,555 hours total).Worksite: Main 24-hour construction gate for the Gamuda Sydney Metro infrastructure project.Shifts: Fixed 12-hour night shifts only (6:00 PM to 6:00 AM).Roster: Alternating weeks of 48 hours one week and 48 to 72 hours the next week. Records: I have complete personal timesheets and a detailed hour note log covering the entire 3+ year period. This includes exact dates, days, hours, and unpaid vacation weeks taken. These personal logs must form the primary basis of your calculation. Pay Received: Flat rate for the whole period (mostly cash-in-hand, with a short period of bank transfers at those same flat rates). Rates started at $25/hr, went to $26/hr, and ended at $27/hr. I can provide approximate dates for when these flat rates changed to help with your calculations.Missed Entitlements to Calculate:I received NO superannuation, annual leave, overtime, overnight rates, weekend rates, or public holiday rates. You must calculate the missing difference across four historic financial year brackets including: Compounding 30% permanent night shift loading on ordinary hours.Compounding 150% and 200% daily and weekly overtime triggers.Weekend and public holiday penalty rates.Accrued annual leave entitlements.Missing superannuation guarantee percentages across the historic financial year changes. Dual-Scenario Output Required: Scenario 1: Security Services Industry Award 2020 [MA000016] calculated strictly at Security Officer Level 3 (due to ongoing on-site training duties for new guards), including the mandatory weekly Supervision Allowance. Scenario 2: Building and Construction General On-site Award 2020 [MA000020] due to specialized construction tickets utilized at the infrastructure gate (Traffic Control, Personnel Hoist, Work Safely at Heights, and Tunnel Induction). Please quote a single fixed price for the completed project. All raw data and documentation provided must remain strictly confidential under Upwork's terms.
