Why don't they have a "would you like to change the flag?" question first, then spend millions on this.

My bet is they either keep the current flag or opt for the second one, which uses the same colours but replaces the Union Flag with the Fern. Choice no. three is supposed to be an unfurling fern but it could just as easily be a stylised breaking wave or a piece of Celtic Art and the last Flag looks like the logo for a Rugby team.
