Looking for a spare room or buddy-up

Hello! I am a 24 year old Australian looking for a room in a flat share or to buddy up to get an apartment together with 1 or more people. I have been living in London for 4 months, working at a start up in Surbiton. Location wise, I am looking anywhere near transport in South London or possibly Hackney/Dalston area. I am a clean and organised flatmate who has been living in shared accommodation for 6 years. My current lease ends August 28th but I am somewhat flexible around dates earlier or later. Absolute max budget is £700 but ideally would like to be at the £550-£650 mark. Please get into contact if this sounds good to you!
