Aussie team boss to examine Rio security ahead of Olympics

Just 24 days out from the Rio Olympics, athletes have been warned to steer clear of "no-go zones" in the Brazilian host city.

Australian chef de mission Kitty Chiller says she won't be afraid to demand better security at the Rio Olympic Games if she doesn't think it's up to scratch.

Ms Chiller's comments come after her plea to Games organisers to tighten security in Rio de Janeiro after an Australian Paralympian was robbed at gunpoint was ignored.

"I'm normally not afraid to speak up," Ms Chiller said today at the women's basketball team announcement on the Gold Coast.

"We're going over there to get medals, but at the end of the day, primarily, we have to bring everyone home safe and sound and well."

Ms Chiller said she was disappointed not to receive a response at all after earlier this month writing to Games organisers demanding extra security be brought on ahead of the event's August 5 opening.

Her move came after Paralympian Liesl Tesch and team physiotherapist Sarah Ross were robbed while training in Rio.

Ms Chiller said some extra troops were being added on Friday and she would be scrutinising security provisions when she arrived in Brazil.

"It will be very interesting for us to see in the first few days what that looks like and to make sure that we're comfortable with it," she said.
