"Dont worry. Melbourne to Sydney is not too far" - There is no student discount, unless you can get one from 'student travel agency (STA). But still this card doesn't work most of time. You need to be resident-student to get real student discount, otherwise you gotaa pay the full price. And dont worry, they are not that expensive. You can afford it easily. - Go by plane if you want a real shortcut, if you can't wait to see your wife.(How come you two a're going to two different cities?). Anyways, it takes an hour and half, costs around 200bucks. - Go by train if you are tired and sleepy coz there is nothing to see except wide countryside. It takes about 8 hours, costs around 150bucks. - Go by bus, catch the ocean route if you want to see the real beauty of Australia, it's amazing. It takes about 10 hours, costs around 120bucks. - If you planning on frequently visiting your wife then apply for a 'frequent flyer' card from any airlines. The more you buy, the more you fly. - If you know how to drive (if you are new in Melbourne, you can use your Nepalese license for six months). Costs $30 a day to rent a car and around $70 for petrol. Its wise idea to go for a drive if you are travelling together. Driving from Melbourne to Sydney via Lakes Entrance is awesome drive. All the roads are safe and all the views are fantastic....It's 963kms and it takes 9 hours by car. I have travelled Melbourne to Sydney lots of time. I have clicked lots of photos along the highways and beaches. Check them out later, i'll be uploading.... Good luck, I might see you in Melbourne later on....
