Decking issues

Recently extended and redecked a smallish deck 10 x 5 on the longest edges. Looks the goods as it incorporated replacing the external wall of the house, installation of 3500 WRC sliding door and lots of $$$$ of spotted gum and stainless screws.

My issue is this.

tracking down 190 x 35 or 190 x 45 spotted gum in a 5800 length as it has a structural role with ballistrading supports etc.

The longest I can find is 3900 190x45.

Any ideas of Melbourne timber merchants that carry the length needed or an alternative proper substitute for spotted gum in the profile/length I need?

cheers
