I wanted to test if an increase in positive cases from overseas was a contributing factor to incursions.

Since 27 Oct NSW have experience 6 HQ breaches

Most breaches occuring at quite high 7d averages (6.6, 5.6, 6.6, 4, 6.1, 6.6).

Current 7d average is 9 cases per day.

Due to numerous pauses in the program, the VIC numbers are quite low.

Breaches at 0.9, 1.1, 0.7 cases per day.

QLD case average has increased in the last month due to outbreaks in PNG, with the Princess Alexandria breach occuring at 4.4 and 3.6 cases per day.
