We designed it using the Blackbutt timber. Just need to a coat of oil once the weather calms down. . . . A Durable Australian Hardwood and is grow in NSW and QLD. Blackbutt is a Fire Resistance Hardwood, which due to its quick growth and versatility, blackbutt makes a good plantation timber. . . #blackbuttdecking #deckingsydney #sydneydecks #decking #benchdeck #backyarddecking
