Anyone know where I could find some good Austrialian soldier models?

Basically i’m been pondering doing some screenshots in the austrailian outback using some old WW1/2 Aussie soldier models, with the bush hat and shorts and all that jazz. Anyone know where i could find some, or if all else fails, any tips on designing the models?

I put together WW2 Australians for Rising Storm Singapore:

I was planning to port them but never quite got around to it, so here’s the raw files if anyone wants.

Absolutely fantastic. Great models. Thanks for the help
