<human>: Give me the gist of the text in a nutshell

At present I am living rent-free at my brother's apartment in Sydney, Australia. It might be the couch but it's worth it until I get a job in the city and move to a hostel. I am 18 years old, male, on a gap year. I've gotten open-dated tickets to go traveling up the east coast, but I'm not going until summer comes around. 

As I have no responsibilities at this time, until I get a bar job (of which I have submitted several applications, waiting to hear back on them), I was wondering what Reddit thinks I should do with the free time that I have here. Moreover I'm interested to hear what people themselves would do if they were in my current situation, and from those that are in a similar situation, what they are currently doing.
