Hi, i'm a 20 year old guy and I decided on the fly to go and do a WH this week and now VISA is done and Flights are all booked. I'll be arriving at about 9:30pm on the 7th of November in Melbourne and i'd really like to meet up with someone in the city just so I don't get too overwhelmed all at once (I've never been to Australia before). Can anyone recommend a good hostel for me to book into and anyone fancy meeting up with me somewhere in the city on the scary first night or more realistically considering i'm flying with China Southern airlines so i'll probably be delayed anyone available to meet me during the day on the 8th?
