G-day prsad,
I agree with serfty but if you get to Albury you will have had an easy 6-7 hour drive (not forgetting to stop at Holbrook to see the sub) and passed the undivided road section. There are many places to stay at and many places to be fed and watered. The following day you can pace yourself for an easy thee hour (approx) drive into Melbourne. This should get you there around lunch time and you cannot check into your hotel before 2pm in most cases, so no need to rush it.

Enjoy the journey

ps did you use the vroom web site to hire your car?

Have fun, Ray
