Mr Morrison told parliament on Wednesday the government's priorities included responding to the COVID-19 pandemic and finalising laws to shield religious Australians from discrimination legislation.

"The exposure draft legislation on these (integrity commission) matters will be made available very soon," he said.

"(It) will be available for people to give their responses to and we'll see whether that has support."

On behalf of Attorney-General Michaelia Cash, Communications Minister Paul Fletcher said nearly $150 million had been committed for the integrity body to have a staff of about 172.

The proposal has previously been criticised as worse than nothing by former NSW Court of Appeal judge Anthony Whealy.

Mr Morrison in October cited the resignation of former premier Gladys Berejiklian over a corruption probe as a reason not to have a NSW-style federal integrity commission.

The coalition earlier said it was committed to introducing a federal integrity bill to parliament this year.

The final scheduled sitting day of 2021 will be next Thursday.
