Maybe something like this site would suite your needs?
P.S. I know many people who have done this. In the mining industry, the company moves your stuff and usually pays for about 3 months of accommodation so you have time to find your bearings.
The company will bring you over on a long stay work visa which allows you to apply for permanent residence.
There are then two options, you can go with a company sponsored permanent residence or an independent permanent residence visa.
I personally have done the latter path. When I was on the work visa my company paid my health insurance and moving costs. The process of immigrating to Australia was very easy but a lot of paperwork.
Australia also needs trades people and has a list of jobs with scarce skills. Check the list and see if your occupation is on it.

If your trade is on the list you can easily get a company sponsored visa to Australia. This is a good pathway to Australian permanent residence and citizenship.
Botswana fits your list
