Inside track

Lindsay, no, there is no access. When were you planning on travelling? As you are probably aware - this area is still flooded and will be for some time. There is another flush coming down the Diamantina at the moment and is presently at Monkira (due to rain north of Winton recently).

The other week there was a post discussing the track closure possibilities for the area from various parties with local contacts.
Re the Warburton and access from the south it was thought that as it was last year the warburton crossing would be closed for the duration as there had been more water this year and as Ruth said it is still coming.
Going on past experiences it may be that even access via the QAA could be out till late in the season either around your proposed date or even later.
If the water stays around you may have to do a loop from the west as is the case at the moment or obtain permits for the Hay river track and head up to Jervois for fuel.
Might have to keep a very flexible itinerary ;-))
