Deputy Premier Jackie Trad has been referred to the State Parliament’s Ethics Committee over her purchase of an investment property at Woolloongabba.

The committee will examine whether Ms Trad failed to include the property on her register of interests within the correct time frame.

The property had the potential to grow in value due to its proximity to the Cross River Rail Project, which Ms Trad was overseeing.

While Queensland’s Crime and Corruption Committee did not find evidence to prove corruption, they referred the case to the Ethics Committee for further consideration.
