Mouse Plague extent?

We intend travelling by caravan from Victoria, thru Echuca, via the Kidman Hwy to Cunnamulla, thence thru Longreach to Cloncurry, on to the Barkly Tablelands. We normally camp out most nights.

Our eventual destination is thru the Kimberly, then Pilbara to Albany and Esperance, then east to Victoria. We have done this trip using different roads 4-5 times.

Having experienced a few mouse plagues when living in the Wimmera, I would prefer not to tangle with the little blighters unless necessary.

We can travel in the opposite direction, but as camping on the Nullabor at the end of the trip, is always a highlight, would prefer the anti-clockwise route.

Does anyone know if the mice have cleared the Kidman, Landsborough route at this time? Are there mice in the Mnt Isa/Camooweal area?
Are there mice on the Barkly Tablelands?

Am I correct in assuming that the country south of Coober Pedy is vermin free?

Any help you can give with these questions will assist, as we are due to leave this Friday, and will be at about Bourke by Sunday, if we go that way.
