It is the 492nd most-seen of the 742 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bark Cockroach in Sydney on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Bark Cockroach is recorded against all the insects logged in Sydney (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
