I'd love to cycle with you or anyone else for that matter. Unfortunately, that won't happen anytime soon. Still need to work. I host a lot of cyclists through the warm showers website and I'm always amazed at the wonderful people I've met through it. I suggest you sign up there and start looking for places to stay. You'll meet lots of like minded people once you're on the road. Have a wonderful adventure!

Try the Brisbane bicycle touring association https://www.bbta.org/ we rode with them a couple of times when we toured Queensland in 2008 with the Cycle touring association of western australia. Good folks, will give you a chance to try a bunch of different rides and learn about what does and does not work in regards to bikes and gear. It would also be a chance to meet potential ride partners and make sure you are compatible travelling buddies before heading off into the unknown. The adventure cycling association in the USA also has a section in their magazine and online for finding touring partners.

This girl I met in South America had cycled solo in Southeast Asia. You might read her journal to see what it's like to cycle solo in SEA.

Someone else already mentioned it but try posting this on Crazy Guy on a Bike? You might have luck there.

Maybe I'll see you on the road over there.

I was about to ignore this thread because you said you were traveling on a push bike, never having heard that term I assumed it meant some sort of kids scooter!

Anyways, I will be touring in Thailand, Vietnam, Laos, and Cambodia at the end of March. I wouldn't mind a traveling partner for at least part of the trip. Send me a PM if you want.

Are you serious ... you've never heard that term for a bicycle? It's used in both Australia and the UK. Not a good description for a bicycle, but what can you do ... that's what non-cyclists call it.

Nope never. I grew up in Arizona, where we mostly just called them bicycles or bikes. Sometimes steeds.

CTC in UK is 100 years old , and, may also be useful , to join , membership,

ACA, in the us is another one , was Bike Centennial,
