Redland residents who have not had the chance to fill out a survey from Bowman MP Andrew Laming will get the opportunity on Thursday (August 6) from 4pm till 6pm.
Mr Laming will open his office for those who have not yet filled out the forms, which include a question on marriage equality.
In June, Mr Laming said if the Abbott government was given a conscience vote on the marriage issue, he would vote in accordance with the outcome of his survey.
When parliament resumes next week, it is expected the multi-party Marriage Equality Bill will be introduced on August 11 and will be discussed in the Liberal party room on August 18.
Mr Laming took to Facebook to notify residents of the opportunity. "Open office: If you haven’t received your same-sex marriage survey drop by my office (32 Middle St, Cleveland) from 4pm till 6pm this Thursday, August 6, to cast your vote."
The Facebook post says ID would be required to ensure no double-ups.
