if u are in Australia, recommendation could try airbnb. youth hostel. or visit on Gumtree(Or u can try some CITYNAME plus BBS, like adelaideBBS, its a website for chinese people who lives here) they might have room for short term stay. Travel place for summer now could try start from mel and sid(then u see the main city of Australia) , then all the way up to north to brisbane, they got golden coast and sunshine coast, and then to cairns.
