Where on earth would I buy 8 inch by 1 1/2 inch hoop pine?

Use to have a mill down the road,living on the Blackbutt Range QLD,they use to cut hoop pine all sizes.



Its all gone now.Have no idea where I could get a few bits of 8 by 1 1/2 to make some squatters chair back legs.

Any suggestions of where to buy would be good (S.E QLD)



thanks
