Former Queensland union boss Dave Hanna has been jailed for at least three years for raping a woman after they met at a Brisbane bar.

The former CFMEU state president was found guilty on Friday of raping the younger woman three times when she was too drunk to give consent in March 2017.

Hanna met the woman at a Fortitude Valley bar then went home with her in a taxi after she had been kicked out of the venue for intoxication.

He knocked down her townhouse door because she had lost her keys and followed her into her Taigum home, in Brisbane's north, and raped her.
