From what I've heard, Prof. Hendy says there'd have to be a lockdown, but Prof. Baker said we'd have to go to Level 4 lockdown. My personal opinion is that Prof. Baker is a bit of an alarmist who produces highly click-bait headlines in the MSM.
I expect that if there was a more-transmissible outbreak, the region in which it occurred would go to Level 3 and the rest of the country to Level 2, like last time.
If the outbreak appeared relatively contained, I wouldn't be surprised if the 'uncontaminated' island went back to Level 1 after a fortnight.
There would have to be a widespread outbreak - on the verge of out of control - before we'd go to Level 4
That makes a lot of sense. Although I feel L4 would be better the next time around as we can prepare for it. Stock up, movie up, and prepare things to avoid any stay at home issues that shook some of us last time. L4 would be shorter, than an ongoing L3.
