Hi Anj,
Don't forget that the moderators (myself & Dolly) and several other forums members are in Australia and there is a difference in time zones. If we're at the computer the reply may be quick but sometimes it will be a while. Today (Friday 25th) is a public holiday here for ANZAC (rememberance) Day.
I don't know what shipping companies there are in New Delhi but the ones we had in the UK were very good. Only one thing got broken and that was something I'd packed myself
Depending on where you are in Melbourne there will still be traffic jams although possibly not as bad as in India. I remember being in very long traffic jams in Calcutta.
We spend about $800 a month on food and bills for 2 people. You need to add your rental costs (there is link to property websites in the "Please read..." post) and also any transport costs (tram, train, possibly hiring a car). When you rent you'll be asked to place a bond and that may be a months rental. So really you need enough to cover 2 months rental at a minimum.
If you are looking for really cheap accommodation search for backpackers accommodation in google for Melbourne since that will be cheap.
Regards,
Karen
