Similarly just walk east along a road that has an on-ramp onto the freeway, the walk should take a maximum of 15 minutes. Its pretty doable to get to Sydney within the same day as long as you leave Melbourne early enough in the morning. Follow the signs to Seymour (Road 55) and don't get confused with the different numbers on the signs, Seymour should be always right. Alternately, you can catch a 40 minute train from Melbourne Central Station or Southern Cross Station towards Seymour to Wallan. Wallan is just outside Melbourne and from the train station it's a 10 minute walk straight onto the Hume Highway. If you're headed to Canberra follow the directions above onto the Hume Hwy. Once you have a lift that is taking you to Yass or further it's best to ask the driver if he/she can take you into Murrumbateman (a small town which is a 10-15min drive after the exit onto the Barton Hwy (25) off the Hume Hwy). From there all traffic must slow down and (if you're coming from Mel) it'll be late in the day when everyone is commuting back to Canberra. Alternatively, there is a large service and truck-stop station just outside of Yass but if it's late in the day most people are commuting back South and it could be awhile (and dark) before you find someone headed into Canberra.
