Australia-bound passengers should check into a trio of bus passes offered by Greyhound Australia.
The Greyhound Australia bus pass allows unlimited travel and can be purchased for 7, 10, 14, 21, 30 or 60 days. The rates are about $92, $122, $143, $192, $272 and $408, respectively. You can get extensions for about $15 a day, but you have to make arrangements for this before the expiration of the original ticket. Your pass starts on the date you first use it to travel.
If you want to combine accommodations with a bus pass, look into the Great Bus-Pass. You can buy this pass for 7 days of bus travel with accommodations for 5 nights, 10 days with 7 hotel nights, 14 days with 9 hotel nights and 21 days with 15 nights. All accommodations, on a double-occupancy basis (you pay extra if traveling solo), are at Flag Inns. Rates are about $165, $223, $278 and $417, respectively.
Under this program you book your first hotel night in advance, then you can plan the rest of your journey as you wish. You get vouchers for use at the other hotels. It's a good idea to book your bus travel in advance.
