The marriage-equality issue has warmed up in the Redlands, with the wife of LNP Oodgeroo MP Mark Robinson putting a poster reading “it’s OK to vote no” on the electorate office window of the Labor Capalaba MP.

Capalaba MP Don Brown said his office was defaced on Saturday with the poster.

Julie Robinson was caught on CCTV posting signs on the Labor MP's office.

Federal Liberal MP Andrew Laming waded into the tiff on social media, labelling Julie Robinson a “hero amongst us this weekend”.

Mr Laming said Mr Brown had taken a brave stand against “two ladies and a blu-tack sign”.
