Can you tell me if there are any recent trips to the Great Ocean Road or Melbourne? I would like to ask about the temperature and clothing index suggestions ?

When it's windy during the day, wear a windbreaker. When it's not windy, wear a T-shirt. At night, it's a bit cold, so wear a thin down jacket.

Depends on which month you go. I went twice and the wind was super strong. Wear a windbreaker. Girls should tie their hair in a bun otherwise it won't look good in photos.

It's a little cool in the morning and evening, so you need to wear a thin long-sleeved jacket. But in the afternoon when the sun is shining, you'll need to switch to a short-sleeved shirt as the temperature goes above 30 degrees.
