Supplements to the Australian Standards
Roads and Maritime Services have developed supplements for Australian Standards AS 1742, 1743 & 2890.
The Supplements document any mandatory Roads and Maritime practice and any complementary guidelines which need to be considered.
Roads and Maritime Supplements must be referred to before using the Standards.
If any conflict arises, Roads and Maritime Supplements, the Austroads Guides and the Australian Standards are to prevail.
