Nah its 4 hours tops.
If your doing the speed limit and don't stop for long you'll do it in 3 hrs easy. Just that every time I went we seemed to find a way of stretching the travel time whether we wanted to or not.
One thing you might want to check if your planning on camping at Mungo, and diving at seal rocks, is whether the rd between the two is open. Last time I went there the dirt road was gated and locked (thanks to our 'friends' at NPWS
) so you might have to go all the way back to the highway and around.
