Innamincka

As well as what Stephen as said, there are also other websites that you can access with regard to road closure information. I would also try contacting the Innamincka Hotel for the latest information regarding access.

Macca.

The only problem Macca, the Strezelecki Track from Innamincka down to Lyndhurst is open to 4WD, but with our crazy weather here in South Australia at the moment, it will not take much rain to close it again.

For any Outback tracks here in South Australia, this is the only site to trust, as if it shows closed, the tracks are.
The only site to fully trust for South Australian Outback Roads.

Thanks for the links guys.
Bit of a depressing read though.
