How overtime pay works in Australia

Overtime in Australia is governed by the National Employment Standards (NES) and modern awards. Once you exceed your ordinary hours (typically 38 per week or 7.6 per day), additional hours attract a penalty rate. The first 2-3 hours of weekday overtime usually pay time and a half (1.5x), then double time (2x) after that. Saturday and Sunday work attract their own penalties — and casuals add the 25% loading on top of all of these.

The calculator above does the maths from any base rate. Below explains how the penalty bands stack, when overtime kicks in, and what to do if your payslip doesn't add up. For just the multipliers, see our time and a half calculator.

Standard overtime structure

ScenarioPermanent rateCasual rate (×1.25)
First 2-3 hrs weekday OT×1.5×1.875
Remaining weekday OT×2.0×2.5
Saturday work×1.5×1.875
Sunday work×2.0×2.5
Public holiday work×2.5×2.75

Rates above apply to most modern awards. Some awards (Banking and Finance, Hospitality salaried roles) have variations — check yours.

When overtime kicks in

Overtime triggers when you work beyond your ordinary hours, but the trigger condition varies:

For part-time employees, overtime is for hours above the agreed weekly or daily hours in your employment contract — even if those are well below 38. A 22-hour/week part-timer asked to work 26 hours would receive overtime for the extra 4 hours under most awards.

Reasonable additional hours

Section 62 of the Fair Work Act allows employers to request "reasonable additional hours" beyond the 38-hour standard. Workers can refuse if the request is unreasonable. Reasonableness is judged on:

Routine excessive overtime, last-minute demands without compensation, or overtime that risks safety can be unreasonable. Employers cannot punish you for reasonable refusal — that would breach workplace rights protections under the Fair Work Act.

Worked examples

Example 1

Full-time retail, $30/hr base, 6 hours overtime in one weekday.

First 2 hours at time-and-a-half: 2 × $30 × 1.5 = $90. Remaining 4 hours at double time: 4 × $30 × 2 = $240. Overtime total: $330. Compared to ordinary pay (6 × $30 = $180), the penalty adds $150.

Example 2

Casual hospitality, $32/hr base, 8 hours on Sunday.

Sunday casual rate (typical): $32 × 2 × 1.25 = $80/hour. Total for 8 hours: $640. Sunday rate already factors in casual loading; don't add it again.

Example 3

Part-time clerk, contracted 25 hrs/week at $36/hr, asked to work 30 hrs one week.

First 25 hours at ordinary rate: 25 × $36 = $900. Additional 5 hours at time-and-a-half (under most awards): 5 × $36 × 1.5 = $270. Weekly total: $1,170. Overtime triggers at the contracted weekly hours, not the 38-hour full-time threshold.
