National Cabinet, which includes Prime Minister Scott Morrison as well as premiers and chief ministers, agreed to the ban following a meeting late on Tuesday. It is important that they get access to these normal services. However, Mr Morrison maintained "it is safe to send your children to school".
But Mr Morrison has defended the government's approach.
The measures - which Morrison said each state may manage differently - include a complete ban on all overseas travel.
"We don't want to be overly specific about that, we want Australians to exercise their commonsense so that means bbqs, of lots of friends or even family, extended family, coming together, to celebrate one-year-old birthday parties and all those sort of things, we cant do those things now".
"People only listen to those that they trust, otherwise they have no reason to agree to the requests to monitor their own behaviour or take certain actions that are being made of them", she said.
Boot camps and personal training must be limited to 10 people.
"You can see what we're trying to do, we're trying to limit the gathering of people in large numbers that can relate to the transmitting of the virus through those social interactions".
An expanded list of businesses will be forced to close their doors at midnight on Wednesday with an emphasis on stopping large gatherings as COVID-19 infections in Australia double every four days, reaching 2136 earlier in the day.
"House parties where someone wants to now have the social events, not at clubs and venues like that but to organise a party at someone's home, the states and territories will be particularly looking at that one and consider whether they'll specifically put measures in place that could lead to that being an offence for those who have organised those types of events". "I'm not going to do that lightly", he said.
For this, the government needed to approach the public with understanding and empathy for their reaction to the uncertainty, she said, and not aggression.
She compared the public's reaction to the pandemic to their response to New South Wales Rural Fire Service Commissioner Shane Fitzsimmons during this summer's bushfire crisis.
"If you look at Italy and the United States and England we are seeing intensive care units with young people in them", he said. "And he was very clear in his communication as well". "Health has to be the most important thing for everyone!"
"Listening to the PM like everyone here in Australia and what I understood was, "It's essential, unless it's not".
The WHO's guidelines for effective communication draws on six principles: accessible, actionable, credible and trusted, relevant, timely, and understandable.
"You should only go outside your home to go to those essential things I talked about, not to go and congregate in groups", Morrison said.
