NSW Nationals descend on Cowra for AGM

Scores of NSW Nationals delegates and politicians have descended on the country town of Cowra for the party's state conference - though there may be one glaring exception.

It's understood former deputy prime minister and Nationals leader Barnaby Joyce, who was said to have been considering attending the annual general conference, is now unlikely to show up.

The embattled member for New England has been on sick leave since May.

More than 60 motions, ranging from health services to tax policy, are up for debate over the two day conference beginning on Friday.

Deputy Prime Minister Michael McCormack and Deputy NSW Premier John Barilaro are both scheduled to address the conference.
