Sth Africa, Namibia, Zimbabwe, Zambia & Botswana

My husband and I are travelling to Africa at the end of the month from Australia. I’m now concerned we don’t have enough blank pages in our passports for the trip.

We don’t need a visa for Sth Africa, I have our visa for Namibia & the KAZA visa for Zimbabwe & Zambia.

We will be entering the countries as follows:

South Africa

Namibia

South Africa

Zimbabwe

Zambia (vic falls) day trip from Zim

Botswana day trip from Zim

South Africa

Does anyone have an idea on how many blank pages we will need?
