When I changed my name online with the Australian Electoral Commission there were three options for gender "M" "--" and "F"
I put done "--" as legally Im not a woman yet.
I few days later the electoral commissions rings up saying I had not put an option for gender. I explained to them that I thought "--" was an option.
I had Ms as my honourific.
The lady kindly changed my gender option to female without being asked.
Cool hey
