What type of wood is best for planter box?

I want to make a few planter boxes for my home. One will be exposed to the weather and the other will not. Can anyone recommend a type of wood to use and where is the best place to buy it here in Perth? I like the colour of Jarrah but maybe thats going to be too expensive. Our house is made of a rust coloured brick so I would like the colour to blend with that - either in the natural colour of the wood or otherwise by painting it.
