I don't know how these trucks were branded in Australia, but in Canada in 1935 the trucks sold by Chevrolet dealers that were 1 1/2 tons capacity or less were branded as Chevrolet and the Maple Leaf brand was used for 2 ton trucks.
If the truck or chassis was originally from Canada, this chart with series, body codes, capacities and wheelbase as offered in Canada may help to identify your truck.

Series EB on 112 inch wheelbase is Chevrolet 1/2 ton
Series QA on 131 inch wheelbase is Chevrolet 1 1/2 ton
Series QD on 157 inch wheelbase is Chevrolet 1 1/2 ton
Series HX on 141 inch wheelbase is Maple Leaf 2 ton
Series HX on 165 inch wheelbase is Maple Leaf 2 ton
Hope this helps. Tom
