Bushfire live blog: Police confirm 20th death in NSW as Canberra shuts down due to hazardous air quality

The body of a missing 71-year-old has been found on his burnt-out south coast property, taking the NSW bushfire death toll to 20.

Another person has died after a "horrendous" weekend of bushfires on NSW's South Coast, the Southern Highlands and the Snowy Mountains.

NSW Police found a body today on a burnt Nerrigundah property on the state's south coast, the eighth person to die in the region and the 20th in NSW.

In South Australia, a  convoy of army vehicles with up to 100 reservists is heading for Kangaroo Island as the bushfire recovery gathers pace.

The blaze, which has burnt more than 155,000 hectares inside a 300-kilometre perimeter, is still active in some areas.

In Victoria, showers are giving firefighters some relief but hot conditions are forecast to return later in the week.
