Eh, maybe they do, but the media wouldn’t broadcast it. Or start criticising Labor for not taking responsibility for leadership of the country themselves. Maybe a more media savvy person will know if theres a generally acknowledged time period, but the media only put up with new governments blaming the last for a short period. Maybe 1 year?

Labor knows this, and rather than have to explain how government and indeed institutional development works to each journalist, they let the ego’s of the journalists, and their ‘mystical’ knowledge of their readers/viewers interests dictate when that response has run its course.
