Welcome to Malaysia, Bigrr,

There are a few Malaysians lurking on this forum, so hopefully they'll chip in.

I guess it all depends on how far off the beaten track you go.

I'm no expert, but here are some things off the top of my head.

A parang (machete) is useful as a multitool. Get one of the local ones made from truck springs. They may have a wooden sheath or none at all.

Yeah, leather sheaths don't last long.

Bead blasted blades attract rust.

Malaria meds don't always work and they can cause memory loss. I've stopped taking them. Better to wear longs and use repellent at sundown.

If you're going to be in the jungle for some time, yes its important to dry your feet at the end of the day. I've heard that troops are taught to dry their feet at the end of the day, use foot powder and keep a pair of socks dry for days' end and swap them out for the wet ones the next day.

Bamboo is ridiculously useful.

Instant noodles are your friend.

No MREs here but you can buy curries in retort pouches from the Brahim's brand.

I've slept under the stars, in a tent, under a tarp and currently use a hammock. Tents are usually too hot. Many people I know just use a tarp.

If you're really interested in local bushcraft skills, get to know the villagers of the indigenous tribes.

Which part of Malaysia are you at?

I'm not aware of any local dedicated outdoor forums. Most revolve around another activity like off roading, knives, etc.

BTW, you do need to eat durian at some point. Hahaha.
