Parliament returns but public still banned

Lobbyists and former MPs will be allowed back in the corridors of power as parliament resumes for its first two-week sitting since coronavirus hit.

But Parliament House in Canberra will remain closed to the public, school groups and events.

Both chambers will sit from Wednesday to Friday with the usual sitting schedule pushed back a day to make travel arrangements easier following the Queen's Birthday public holiday.

There hasn't been a scheduled Friday sitting since the early days of the Kevin Rudd era.

Top of the government's agenda is a bill dealing medicinal cannabis and hemp exports.

That's expected to sail through the lower house on Wednesday and come before the Senate on Thursday.

Government Services Minister Stuart Robert also wants new powers to ban dodgy carers and service providers from entering the National Disability Insurance Scheme before parliament within the fortnight.

Parliament will also consider laws to establish a national skills commissioner, force big business to report regularly on how promptly they pay small suppliers, and criminalise advertising academic cheating services.

Finance Minister Mathias Cormann will face questions about the $60 billion JobKeeper bungle on Tuesday from the Senate committee examining the government's COVID-19 response.

The committee asked Treasurer Josh Frydenberg to front up but it cannot force ministers from the lower house to appear.

Labor is expected to pursue Mr Frydenberg and Prime Minister Scott Morrison in parliament over the Treasury miscalculation along with their plans for JobKeeper and lifting the nation out of recession.
