The former chief executive of Ipswich City Council, his wife and two businessmen have been sentenced in Brisbane District Court on Friday for corruption.

Carl Wulff, 66, his wife Sharon Oxenbridge, 50, and businessmen Wayne Myers, 64, and Claude Walker, 61, all pleaded guilty in December after they were charged following a lengthy Crime and Corruption Commission investigation into the council's dealings.

Chief Justice Kerry O'Brien says Wulff occupied a position of considerable influence, importance and power. O’Brien goes on to say their corruption extended over a lengthy period of time and the amount of money involved was considerable.
