I remember it has been done on The Block and I saw it in a real estate listing just recently, so the guess is yes, but for a definitive answer perhaps you could ask your local council. FWIW to me it's completely about staging and completely not about safety and practicality and it's not something you can easily undo if you change your mind.

The fitting must be enclosed. My electrician refused to hang my chandelier because it had open bulbs.

Zone 0: Inside the bath or shower. Any Lighting used here must have a minimum rating of IP67 (protected against immersion in water)

Zone 1: Above the bath or shower to a height of 2.25m. A minimum rating of IP44 is required

Zone 2: The area stretching to 0.6m outside the bath or shower and above the bath or shower if over 2.25m. An IP rating of at least IP44 is required

Outside Zone: Anywhere outside zones 0, 1 & 2. Where water jets are not to be used for cleaning purposes, the general rules of BS7671 apply

In addition to the above, if there is a likelihood of water jets being used for cleaning purpose in zones 1 and 2 a fitting rated a minimum IP65 must be used.

Now that this has been explained, always make sure to purchase bathroom lighting according to these standards to make sure that your bathroom is always safe. You should also have this principle applied when you purchase other electrical devices such as heated towel rails, or a guide to where you'd put sockets in your bath for razors and other devices.

This may also fix the common misconception that LED lights are not rated for bathrooms. Typical LED lights have an IP rating of IP66 which is more than the needed IP rating standard that bathrooms should have. - Not to mention you'd be saving a whole lot from energy bills in the long run.
