Maree to Birdsville - March 2005

Ok Guys, time for a newbie type question.

I am going Barra fishing in Weipa FNQ in April 2005.

To do this I need to leave Adelaide in March and would like to drive up the route with the following o/night stops:

Adelaide, Maree, Mungerannie roadhouse, Birdsvill, Birdsville, Boulia, Winton, Hughenden, Townsville, Cairns.

My question is: I am planning to leave on 14 March '05, is this too early for the Birdsville track? Will there be hassles with the roads/tracks further up in SE Qld at that time?

Obviously I will be monitoring the weather and road conditions just before leaving. I have an alternate route planned going thru Broken Hill, Bourke, Moree, Miles, Rockhampton, Mackay. Townsville, Cairns

Looking for general advice to aid trip planning. Will most likely be towing a CT.

Ruth, Can I have a booking for two nights 16-17 March 2005???????????

Thanks guys

Muddy.
