Greyhound 50% off specials - Perth to Darwin, Alice to Adelaide
I am not a greyhound rep but stumbled across their specials page. They have a lot on offer as I guess they try to compete with the discount airlines. Perth to Darwin makes me shudder just thinking about it. Would be ok if you could jump off then jump back on. Don't know if you can do that
The link takes you to the specials page and the offers are divided into states.
All of them expire 30th September
