Finding an original starter cup in Australia is difficult but you could try here
https://vaces.com.au/photos/villiers-parts/Might be expensive so Norms Chonda starter drum may be the cheapest option .
Changing the Villiers starter pawls with Victa pawls is not a good option, I tried a Villiers starter with the Victa pawls and it did not grip the starter
cup enough.
