why is the package CP343046365CN in Australia when I sent all of them from Wenzhou to Namibia? And why are the other three packages stuck in Hong Kong?

You may use ship way to deliver them. So, they transit there.

okay and approximately when will I recrive them?

*receive

It usually takes three or four months for them to reach your place by ship. But I think they are stuck there and not move after that. You'd better contact China Post to reflect your problem.

okay could you please give me the contact details for China post in wenzhou?

Just call +86 10 11183 (then press 8 to get the English service after your hear the voice).

okay thank you very much for your help :)
