Scott Morrison told reporters this afternoon that a "four-square-metre rule" will replace the 100-person cap.
"As you look across the third step, you will note a series of caps for indoor gatherings of 100, and that can be anything from funerals through to the number of people who can be in a premises, or even in a room such as this," the PM said.
"That 100 cap for Step 3 across all of those areas will be removed and it will be replaced by a four-square metre rule application."
He gave Premiers and Chief Ministers an ultimatum on reopening borders, saying states that want to bring international students in cannot do so unless they let Australians in.
