How does public reporting work in the ASIC Jurisdiction?

ASIC does not have a public ticker but TRs are required to publish a weekly aggregate report

The information reported to ASIC TR is not publicly disseminated on a ticker.

However, TR's are obligated to publish weekly aggregate statistical data. 
Per https://www.legislation.gov.au/Details/F2022C01235 Section 2.3.5

KOR must, for each 7-calendar day period (Relevant Period) commencing from the day KOR first accepts a report of Relevant Derivative Trade Data, create the following statistical data from the Relevant Derivative Trade Data:

1. all aggregate open positions as at the end of the last day in the Relevant Period for which the statistical data is created; and

2. volumes by number and by value of Derivative Transactions reported during the Relevant Period.

The statistical data must include breakdowns by the following categories (if applicable):

1. the asset class, currency of the notional amount, type and maturity of the Derivatives to which the statistical data relates;

2. the geographic location of the reference asset, rate, index, commodity or other thing underlying the Derivatives to which the statistical data relates; and

3. whether the Derivatives to which the statistical data relates are cleared or uncleared.

KOR must disclose the statistical data in relation to a Relevant Period, from a day that is between 3–5 business days after the day on which the Relevant Period ends.

KOR must disclose the statistical data by making the statistical data available at no charge and through a publicly accessible website which is available on www.korfinancial.com.

The statistical data published must not include Derivative Trade Data capable of identifying a counterparty to a Derivative Transaction.
