The Northern Territory has detected 517 new COVID-19 cases as the virus continues to spread through remote Indigenous communities.
NT Health reported 31 infections in Galiwin'ku on Elcho Island in Arnhem Land with the outbreak there growing to 118 cases.
Eleven new infections were detected at Yuendumu, northwest of Alice Springs and seven were recorded at Amoonguna, also in central Australia.
Fifteen cases were found in locked-down Milikapiti, bringing the total number of cases in the isolated Tiwi Island community to 21.
Another 26 cases were found in Mission Australia's Darwin homeless shelter, adding to the dozens detected earlier in the week.
A cluster in the Alice Springs town camps grew by 17 and an outbreak in the local prison surged with 23 new infections diagnosed.
Cases were also reported in Gunyangara, Nhulunbuy, Yirrkala, Wurrumiyanga, Ntaria, Santa Teresa and more than a dozen other Aboriginal communities across the NT.
About 3200 cases are currently active in the territory and 72 patients are in hospital with the virus. Ten require oxygen and three are in intensive care.
About 30 per cent of the territory's 246,500-strong population are Indigenous.
The NT detected 286 cases on Monday, 212 on Sunday, 314 on Saturday, 432 on Friday, 459 on Thursday, 418 on Wednesday and 625 last Tuesday.
