Wynnum sits right on Moreton Bay, roughly 30–35 minutes from our Archerfield warehouse — we deliver out to the Wynnum/Manly waterfront regularly. Being this close to the bay, salt air is a genuine factor: it speeds up corrosion on lower-grade fixings and means timber decks need more frequent oiling than an inland suburb would.
As Merbau Specialists we supply Merbau decking, hardwood posts, and battens, plus a Made in Australia Composite Decking range for those after a lower-maintenance option.
