The body of missing woman Allison Baden-Clay is believed to have been found 11 days since she was reported missing. Authorities have yet to make a confirmatory announcement, but Baden-Clay's family has been informed of the latest developments, according to The Courier-Mail.

Initial reports indicate the woman's body was found at Mt Crosby Weir, which is a 20-minute drive from the Baden-Clay family home in Brookfield.

Baden-Clay, 43, mother of three young girls, was last seen 11 days ago in Brookfield. Her husband, Gerard Baden-Clay, reported her missing before hiring a Gold Coast criminal lawyer.

Police has done an intensive search for Baden-Clay, involving more than 80 officers and 50 SES volunteers. Air and ground search efforts were made, but the victim seemed to have just vanished without a trace.

As police made their way to the site, traffic leading to Mt Crosby Road has been re-routed from Hawkesbury Road to Tandera Roads at Anstead.
