A lot of commenters in the blog have been pointing out that Victoria's lockdown roadmap is stricter than other jurisdictions — and if NSW was subject to Victoria's restrictions, it would be locked down right now.
Myself and some others I've been talking to seem to all agree Victoria's road map is ultra-conservative and open to relaxing depending on the nature of the transmissions. If it hangs around in the disadvantaged, poor, vulnearable (pick your adjective) and/or recent immigrant communities it's difficult to see the timelines changing much at all. If the unknown sources can be eliminated then it might move faster, but before the announcement, everyone wanted certainty so they could plan. Well this is certainty, with the rider that if it reduces faster than expeceted - it's a bonus. The trouble is it's just not the sort of certainty people wanted.
