ABC has a some reporting I found on their AM radio show page quoting Mr Wilson:
The more I have thought about it, about what I personally believe in according to my faith, unfortunately I can't support the bill.Labour allowed a conscience vote*, but LNP voted as a bloc. Possibly this answers the question of how Dale Shuttleworth, LNP candidate for Ferny Grove would have voted.
* In theory a sitting member of parliament can vote however they choose on an issue at any time, but they risk the ire of their party apparatus if they do. A 'conscience vote' is one where the party acknowledges that party unity must occasionally take a back seat to the personal beliefs of the members. I wonder when sitting members vote solely on the needs (or majority views) of their electorate.
