Governing body FIBA announced on Wednesday that Basketball Australia (BA) did not violate its internal regulations during a 91-83 Group D defeat to Angola on September 6 in Gran Canaria.
Australia were investigated for the manner in which they lost to the Africans, after key duo Joe Ingles and Aron Baynes - both plying their trades in the NBA - were rested.
The loss ensured Australia avoided eventual champions Team USA until at least the semi-finals, though the Aussies subsequently bowed out of the tournament against Turkey in the round of 16.
"We are very happy to announce that our investigation has cleared Australia of violating the Internal Regulation," FIBA Secretary General Patrick Baumann said in a statement.
"As one of our most active national member federations across men's, women's and youth basketball, we know we can count on Basketball Australia to wholeheartedly endorse the principles of fair play and ethical behaviour outlined in FIBA's Code of Conduct and Fair Play."
