Travel directions - Perth to Mt Augusta

I take it you mean Mount Augustus 4 runner. There are variables within these options. Are you looking to maximise sealed roads or do you want to take the quickest route?

As a starter have a look at this Trek Note Pilbara/Paraburdoo_to_Murchison_via_Mt_Augustus

taking the dirt could be a better option to get away from the heavy haulage on the bitumen.
the dirt roads are supurb and as good or better than bitumen anyway.
I just headed North from Yalgoo, dirt road all the way , very little traffick

I would suggest that the least dirt road route would be via Meekatharra. Others will be able to tell you what the road is like from Meekatharra to Landor Station, but i think it is reasonable. From Landor to Mount Augustus is the stony tyre littered stretch - or it was a few years ago.

Perth to Meekatharra via the Great Northern Highway is 760 kilometres with an estimated nine hours according to my trip planner, and you will encounter heavy haulage. 337 kilometres of dirt road to Landor should be OK at you dirt road speed. The 100 kilometres to Mount August from there would need to be taken slower if still as we found it.

I hope this, together with the other suggestions in the thread, assists you to work it all out.

4 Runner

The road from Meeka through Landor was fine back in November although they have had some rain out that way a few weeks ago, If you want sealed roads as much as possible, you could come up via Carnarvon out to Gassy Junction which would leave only a couple of hundred k's on the dirt ,which is ok as well . Would be quite a bit further via Carnarvon. The road from Mullewa to Gassy Junction whilst unsealed is generally ok

hi 4 runner
last time i came home from mt augustus
i came down to landor 91 km's good stion rd then xed gascoyne rvr and onto public rd to glenburg 100k's
then onto murchison rd house 187k's where you can camp
out the back near an oval
from there to mullewa 201k's
sealed rd started just north of mullewa
all the gravel rd just north of mullewa was well maintained and i cant see for the life of me why it would be any problem to your bus its a wide rd and i counted less than ten vehicles on it for the entire trip daytime only that i did
but with new mining developements there could be a bit more traffic these days some one else may know
and from there you can choose to go 99k's to geraldton to the northwest coastal brand hwy
or 64 k's to mingenew and follow midlands inland rd -three springs -carnamah - moora to bindoon and muchea all sealed either way
you could also turn off brand hwy at freshwater pt south of dongara and follow the new section of coast rd down to the wanneroo rd and into perth if you choose a coastal drive
cheers
