Sure, but look at NZ - they are far smaller and less densely populated but appear to be ahead of us.
WA being far enough away from the east coast and with relatively few cases could well stay out of a full lockdown for some time lockout but I hope not.
BTW for those that not aware, if anyone thinks I'm paranoid I'm 65 with a 4 co-morbidities. If excrement hits the ventilator I won't even get close to one..
