Before the end of each calendar year the following amounts must be published in the Australian Government Gazette for all child support periods starting in the following calendar year:

  • the minimum annual rate of child support
  • the fixed annual rate of child support
  • the Costs of the Children Table, incorporating
    • the annualised Male Total Average Weekly Earnings (MTAWE) figure, and
    • other amounts in the table worked out using the annualised MTAWE figure.

Before the end of each financial year the following amounts must be published in the Australian Government Gazette:

  • the Average Weekly Earnings (AWE) amount for the quarter ending on 31 December of that financial year.

Male Total Average Weekly Earnings (MTAWE)

Annualised MTAWE figure

The annualised MTAWE figure is the trend MTAWE figure for the relevant June quarter multiplied by 52. The relevant June quarter is the quarter ending on 30 June of the calendar year ending before the start of the child support period. For example, the quarter ending 30 June 2022 is the relevant June quarter for child support periods starting in 2023.

The Costs of the Children Table is constructed using income levels divided at each 0.5 of the annualised MTAWE figure until 2.5 times the annualised MTAWE figure is reached. The Costs of the Children Table is updated each year in line with changes to MTAWE.

Due to the impact of the COVID-19 pandemic on the labour market, the Australian Bureau of Statistics (ABS) temporarily suspended publication of the average weekly earnings trend series from May 2020. In consultation with the Australian Statistician, alternative MTAWE amounts for June 2020, June 2021 and June 2022 have been determined under section 5A(6) of the CSA Act.

Self-support amount (1/3 MTAWE)

The self-support amount is 1/3 of the annualised MTAWE figure for the relevant year.

Default income (2/3 MTAWE)

A default income equal to at least 2/3 annualised MTAWE for the relevant child support period may be used where there is no ATO assessment for a parent for two or more income years prior to the last relevant year of income used in the assessment, or there is no ATO assessment available. For further information see 2.4.4.40.

Act reference: CSA Act section 5A Definition of annualised MTAWE figure, section 45 Working out the self-support amount, section 58 Determination by the Registrar of a parent's adjusted taxable income, section 65A Annual rate of child support for low income parents not on income support, section 66 Minimum annual rate of child support, section 155 Publication of figures

Parenting Payment (single) maximum basic amount

If a parent's income is less than the Parenting Payment (single) maximum basic amount (and other conditions are satisfied), the fixed annual rate may apply. See 2.4.11 for more information on the fixed annual rate and 2.5.3 for information on applications for the fixed annual rate not to be used.

Policy reference: CS Guide 2.4.11 Fixed annual rate of child support for certain low income parents, 2.5.3 Application to have the fixed annual rate of child support not used

ATI indexation factor

From 1 July 2011, child support legislation uses an indexation factor (the ATI indexation factor) where a parent has not lodged a tax return for the last relevant year of income but has lodged a tax return for the previous year of income, or for an earlier year of income.

The ATI indexation factor is calculated with reference to the trend all employees AWE figure for the December quarter (November reference period) published by the ABS and is used in the calculation of assessments where required from the following 1 July.

Note: From 1 July 2011 to 30 June 2013, the ATI indexation factor was calculated with reference to the September quarter AWE figure (August reference period). Due to changes in the frequency of AWE publications, the December quarter (November reference period) AWE figure is used to calculate the ATI indexation factor for all child support periods commencing from 1 July 2013.

The AWE values (used in the calculation of the ATI indexation factor) that apply to child support periods commencing on or after 1 July 2013 are:

Year (November) AWE
2021* $1,328.90
2020* $1,291.30
2019 $1,256.20
2018 $1,225.00
2017 $1,191.70
2016 $1,164.60
2015 $1,145.60
2014 $1,128.90
2013 $1,115.40
2012 $1,080.30
2011 $1,033.30

*The Australian Statistician temporarily suspended publication of the AWE trend series from May 2020. In consultation with the Australian Statistician, an alternative AWE amount has been determined for this December quarter. Calculations of the ATI indexation factor for child support periods that begin from the following 1 July use the determined amount.

Child support inflation factor

Prior to 1 July 2011, the CSA Act provided for an inflation factor, known as the child support inflation factor, to determine incomes to be used in assessments where a parent did not lodge a tax return for the relevant year of income but lodged a tax return for the previous year of income.

Some child support agreements or court orders still specify that the child support inflation factor be used as the indexation value for that agreement or order. These orders and agreements continue to use the inflation factor as per the previous methodology in the CSA Act. Due to a change to the ABS' publication frequency of AWE, from 2013 the child support inflation factor generally refers to the trend AWE figure of the relevant June quarter for child support agreement and court order purposes.

Due to the impact of the COVID-19 pandemic on the labour market, the ABS temporarily suspended publication of the average weekly earnings trend series from May 2020. As a result, the 2021 and 2022 child support inflation factors were calculated with reference to the 12-month period to the December quarter 2019. The 2023 child support inflation factor was calculated with reference to the 12-month period to the June quarter 2022.

Costs of the Children Table

The Costs of the Children Table is updated annually to recognise changes in MTAWE. A new table is published for each calendar year, to be used in assessments for child support periods that start in that year. The table is located at clause 1 of Schedule 1 of the CSA Act. See 2.4.6 for further information about calculating the costs of children.
