Observations carried out 205kms from the Substitute point. The actual degree point is 45kms S of the Qld-NSW border (inability to secure permission to enter property). Site is adjacent to the Macintyre River, part of the Darling River system. As the true point 29 °S 150°E is well into NSW, a substitute point on the Macintyre River was established.

Bridge

The well known bridge crossing the Macintyre River at Goondiwindi is still used, but most traffic moving between Qld and NSW in this area uses the newer crossing east of the town. The Macintyre-Barwon-Darling-Murray forms the longest continuous river system in Australia at 3370km. On occasion the Macintyre, like other river systems, experiences flooding.
