So basically, i'm a hiking/bush walking newbie. I come from England and have only really been on day hikes around the Lake District. I came to Australia in 2009 and have backpacked most of the country, but have only day hiked through the Grampians national park. I met my girlfriend and i'm currently applying for residency and i live in Brisbane. I would very much love to get into bush walking! I'm fairly inexperienced, but fit and healthy and i have good stamina

I would like to try out some day hikes nearby Brisbane (max of about 3 hours away) and then go on to trying some overnight hikes. I don't really know anybody who is into hiking so ill probably be doing it alone. I have been looking at Lamington national park but does anybody have any suggestions of places to visit? or maybe any routes that i could do?
Oh, and another bad thing is, i don't have a car

So yes, basically any information on:
1. Essentials to bring on a day hike then essentials for a 2 day hike
2. Places near South East QLD to visit
3. Any tips or advice!
Thanks in advance! I hope to start as soon as the rain has cleared off for a good while
