Wobu akontaa sɛ nnipa bɛyɛ 5,000 na wonya saa yare yi afe biara wɔ Australia nkutoo.

Ɔkwan bɛn so na saa mmoawa yi trɛw kɔ obi so?

Saa mmoawa yi nam nwansena bi a ɔka no so titiriw. Wɔahu akwan abien a eyi fa so ba.

1. Efi mmoa so kosi nnipa so: Eyi ne ɔkwan titiriw. Fa no sɛ kangaroo, wallaby, ɔkraman, anaa aboa bi te sɛ ɔkraman anya ɔyare mmoawa yi. Nwansena bi ba bɛwe saa aboa no, na afei ɔka wo. Afei mmoawa no fi aboa no mu fa nwansena no mu hyɛn wo nipadua mu.
