[Pre-injury Average Weekly Earnings (PIAWE)](https://knowledge.ausrehab.com/payments-reimbursements?hsLang=en#pre-injury-average-weekly-earnings-piawe) # Must PIAWE be determined by the insurer? ## PIAWE can be determined collectively by a worker and their employer. Instead of leaving the PIAWE calculation up to the insurer, a worker and their employer can apply to use an agreed PIAWE amount (that remains subject to the minimum of $155 per week). The application to use an agreed amount must be provided to the insurer within five (5) days of the [initial notification of injury](https://knowledge.ausrehab.com/what-do-i-need-to-include-in-an-initial-notification-to-an-insurer?hsLang=en) and should include: - the agreed PIAWE amount - the date of the agreement - the worker's name, injury date and claim number - the name of the employer - the name and contact details of the person authorised by the employer to enter into the agreement - details of any other employment in which the worker is engaged - any evidence which supports the agreement (e.g. recent payslips or contract of employment) - any other information the employer or worker considers were taken into account in reaching the agreement - acknowledgement of consent by the worker and employer to the agreement. The insurer must in turn decide whether to approve or reject the agreement within seven (7) days of receiving the application. - [Legal Rights & Obligations](https://knowledge.ausrehab.com/legal-rights-obligations?hsLang=en#main-content) - [Employer Help Desk](https://knowledge.ausrehab.com/legal-rights-obligations?hsLang=en#employer-help-desk) - [Worker Eligibility & Coverage](https://knowledge.ausrehab.com/legal-rights-obligations?hsLang=en#worker-eligibility-coverage) - [Worker Rights & Entitlements](https://knowledge.ausrehab.com/legal-rights-obligations?hsLang=en#worker-rights-entitlements) - [Career Services](https://knowledge.ausrehab.com/career-services?hsLang=en) - [Return to Work](https://knowledge.ausrehab.com/return-to-work?hsLang=en#main-content) - [FAQs](https://knowledge.ausrehab.com/return-to-work?hsLang=en#faqs) - [SIRA Programs](https://knowledge.ausrehab.com/return-to-work?hsLang=en#sira-programs) - [Payments & Reimbursements](https://knowledge.ausrehab.com/payments-reimbursements?hsLang=en#main-content) - [Reimbursements](https://knowledge.ausrehab.com/payments-reimbursements?hsLang=en#reimbursements) - [Pre-injury Average Weekly Earnings (PIAWE)](https://knowledge.ausrehab.com/payments-reimbursements?hsLang=en#pre-injury-average-weekly-earnings-piawe) - [Costs & Payments](https://knowledge.ausrehab.com/payments-reimbursements?hsLang=en#costs-payments) - [Workers Compensation](https://knowledge.ausrehab.com/workers-compensation?hsLang=en#main-content) - [Claim Lodgement](https://knowledge.ausrehab.com/workers-compensation?hsLang=en#claim-lodgement) - [Navigating the System](https://knowledge.ausrehab.com/workers-compensation?hsLang=en#navigating-the-system) - [Eligibility & Coverage](https://knowledge.ausrehab.com/workers-compensation?hsLang=en#eligibility-coverage) - [Key Work Health and Safety Statistics Australia 2024](https://knowledge.ausrehab.com/workers-compensation?hsLang=en#key-work-health-and-safety-statistics-australia-2024) - [Pre-employment Screening](https://knowledge.ausrehab.com/pre-employment-screening?hsLang=en#main-content) - [Booking Process](https://knowledge.ausrehab.com/pre-employment-screening?hsLang=en#booking-process) - [FAQs](https://knowledge.ausrehab.com/pre-employment-screening?hsLang=en#faqs) - [Technical Support](https://knowledge.ausrehab.com/technical-support?hsLang=en#main-content) - [AusRehab Consent Form](https://knowledge.ausrehab.com/technical-support?hsLang=en#ausrehab-consent-form) - [Workplace Rehabilitation](https://knowledge.ausrehab.com/workplace-rehabilitation?hsLang=en) - [CTP (Compulsory Third Party Insurance)](https://knowledge.ausrehab.com/ctp-compulsory-third-party-insurance?hsLang=en) - [Business Information](https://knowledge.ausrehab.com/business-information?hsLang=en) - [ADL (Activities of Daily Living) Assessment](https://knowledge.ausrehab.com/adl-activities-of-daily-living-assessment?hsLang=en) [![Chill listening crop-3](https://knowledge.ausrehab.com/hubfs/AusRehab%20Knowledge%20Base_Logo%20Colour.svg "Chill listening crop-3")](https://www.ausrehab.com) Copyright © 2025, AusRehab
