Trip to Australia and New Zealand in August

Hello,

One of my dreams is visiting Australia. As one of my friends is going to live in Auckland for one year, my friend and I would like to visit this country as well.

We did not book the ticket yet, but we just have one month, August, to go. I was thinking about staying three weeks in Australia. In New Zealand, just one week because It is winter there, and maybe we cannot enjoy the landscapes.

If you have any information, let me know, I really appreciate it.

Thanks,
Sandra
