Does the Speaker of the House of Representatives have to wear a wig?

Thanks for this interesting question.

The Speaker of the House of Representatives does not have to wear a wig but does have the option to do so.

The Speaker usually wears business clothes such as a suit for their daily work in Parliament. However, they may choose to wear the traditional clothing of the role in both the House of Representatives and for formal occasions. This includes a judges wig, a black gown, a jacket, a jabot (lace collar) or white bow tie, and court shoes.

In the past, many Speakers chose to wear all or part of the traditional dress. Since 1988, when the Parliament moved to new Parliament House, no Speaker has worn a wig, although some have worn a black gown. The last time a Speaker chose to wear any traditional clothing in the House was in 2012.
