After 2.30pm a AT spokesman said their contractor was on their way to wash the area "urgently".
According to its website, AT has a cleaning schedule that "varies throughout the region with high-use areas such as the CBD being cleaned continually throughout the day".
"The central city is routinely washed three times a week as well as being swept continually." the spokesman said.
It also says that cleaning mainly takes place during the early hours of the day and involves "mechanically and manually sweeping the footpaths and streets, as well as collecting all the litter".
AT asks that if anyone sees blood, vomit, or anything else on the street they should call them and they will have it cleaned up within the hour.
