A Victorian man has been charged with making corrupt payments of $104,000 to former Ipswich City Council chief executive Carl Wulff and his wife.
Wulff, 66, and his 51-year-old wife Sharon Oxenbridge were charged with official corruption by Queensland's Crime and Corruption Commission (CCC) in April after allegedly receiving the money in 20 separate payments.
The payments related to council contracts, the CCC revealed on Wednesday.
The 60-year-old man is set to appear in Brisbane Magistrates Court on June 13 on one count of corruption.
He is the fifth person charged as part of the CCC's investigations into the council this month, and the 15th overall, alongside Wulff's successor Jim Lindsay and former mayors Paul Pisasale and Andrew Antoniolli.
A total of 71 charges have been handed down.
Wulff and Oxenbridge, who are on bail and are also facing other charges, are set to next appear in court on May 28.
Antoniolli did not appear for the first mention of his seven fraud charges in Brisbane Magistrates Court on Wednesday, when he was ordered not to contact Wulff and Lindsay as part of his bail conditions.
Pisasale, who was charged in June 2017, faces several allegations that include corruption and misconduct.
The CCC's allegations saw Antoniolli stand down a fortnight ago and it also prompted the state government to move to dismiss the Ipswich council.
The state Labor government has been criticised for not acting against the council sooner and on Tuesday introduced a bill in parliament to strengthen the powers of the local government minister to dismiss councillors.
The 11-person council has vowed to fight to stay in power.
