There are 10 entities in the 2020–21 PRRT transparency population, with total PRRT payable of $926 million. The number of entities paying PRRT decreased from 12 in the previous year, and PRRT payable increased from $881.1 million.

The increase in PRRT payable reflects the increased profitability of PRRT liable companies in 2020–21, with oil prices being a key driver, see World Bank commodity prices dataExternal Link.
