Australian timber suitable for floor stringers

[GILow]

Hello cruisers,

I am putting in a new stringers for the cabin sole. Part of a rewarding process of reducing the number of steps up and down in the boat.

I have read lots on CF of various peoples' experiences and advice, but I am having trouble deciding on a suitable timber for the stringers. Most of the suggestions I have found are for timbers not easily found in Australia.

Can anyone suggest some Australian timber types that would suit? The stringers would cross a (usually) dry bildge and have a maximum span of about 3 feet at the widest point, down to 2 feet at the bow. They would be glassed to the hull, at least at the ends, and the cabin sole will be plywood of a suitable thickness.

Ta,

Matt
