State and territory governments will choose when to move through the phases, with the third and final part of the plan set to be in place nationally by July.

Mr Morrison says the plan would get 850,000 people back to work in the coming months.

"You can stay under the doona forever and you'll never face any danger. But we've got to get out from under the doona at some time," he said on Friday.

"If not now, well, then when?"

States can pick and choose which elements of the stages they move on.

Cafes, restaurants and shops will be permitted to reopen under the first stage, which also allows for public outdoor gatherings of up to 10 people.

Five people will be allowed to visit other homes.

Weddings will be allowed up to 10 guests in addition to the couple and celebrant, while funerals can have 20 mourners indoors and 30 outdoors.

Real estate home inspections and auctions can resume with a 10-person limit, while children will return to schools and child care.

Universities and TAFE colleges are set to increase face-to-face teaching, with an initial priority put on skills which require a hands-on approach.

In stage two, non-work gatherings will be allowed 20 people, with the figure increasing to 100 under the third step.

Gyms and cinemas will be allowed to reopen under the second phase.

Pubs and clubs won't be allowed to reopen until the final stage, which will see people return to workplaces on a larger scale.

Trans-Tasman and Pacific island travel could restart in July, but other international borders will remain closed.

Physical distancing requirements will remain in place to limit the spread of the virus, which has caused 97 deaths nationally.

"Step one is tentative, baby steps into normalisation," Chief Medical Officer Brendan Murphy said.

"If everything goes well, we don't have big outbreaks, step two could be more confident."

Professor Murphy said the days of people soldiering on through sickness to work were over.

"We will see a permanent change in that sort of cavalier attitude of going to work when you've got a cold or a flu," he said.

Mr Morrison said moving through the stages would be guided by medical advice.

"When that plan has been implemented, people will be back in work, people will be back together, and Australia will be stronger."

He said there would be inconsistencies between states as jurisdictions respond to different situations.

"States will and must move at their own pace and will cut and paste out of this plan to suit their local circumstances," the prime minister said.

"This is a complex and very uncertain environment. But we cannot allow our fear of going backwards from stopping us from going forward."

Victoria will not relax rules until at least Monday, while NSW is also maintaining a cautious approach with outbreaks active in the most populous states.

From May 16, Queensland will allow dining in pubs, clubs and restaurants for up 10 people.

SA has adopted many of the stage one guidelines, while WA and NT have already relaxed a raft of rules.

Between May 11 and 18 Tasmania will move to most of national cabinet's stage one guidelines.

The ACT has lifted outdoor gathering limits to 10 people.
