I'm off to S.E. Asia in a couple of weeks and will be taking my camera and multiple lenses. Needless to say, it will be humid and rainy. Any suggestions on how best to keep my lenses clear of fungi. Due to space constraints, I can't take a water tight case/box with me.

Zip lock bags.

Dont take off the lens outside.

Fungi can be a problem. But more immediately, trekking through high humidity can shut down your camera.
I would research how to best prevent that and how to prevent fungi that might grow later. Perhaps using dessicant, sun, and look into how to store the camera when not using it.
But I would research it.

Get a camera/lens raincoat for your camera. You can purchase them from B&H, cheap. When you're done with your gear, put everything in your fastened gear bag in the hotel closet, and keep it away from the air conditioning vents. Have a great trip.

Specifically - the problem is going from a cold air-conditioned room out in to the hot humid air - moisture condenses on - and in - your equipment. Keeping them in a zip-lock bag for ten minutes when you go out, letting them warm up without being exposed to the humid air - is a good preventive. I also like to keep silica gel packs in my camera case to help dry things out overnight.

Lots of silica gel desiccants stored in your camera bag will help.

This is correct.
Did a wedding in Jamaica and went from 22degc aircon room to 44degc humidex. Cameras were dripping. In the end, you need to allow for the equipment to come to temperature in a plastic ziplock before you expose to the air or you will have issues. I had both cameras malfunction at various times due to moisture in the camera electronics. Luckily, no permaent dendritic growth. Lenses appear to be fine also but I cant imagine living there and expecting the equipment to survive without some serious moisture management.

Thanks everyone. I really appreciate the great advice.

Carry lots of little silicate packs. I save them when I receive them with products.

Some of the sporting goods stores carry silicate devices made for gun cabinets that plug into standard 110 volt outlets to recharge them. The ones I have have a colored indicator on them and when they turn pink, they are full of moisture and need recharged. They don't do much good once saturated. They are small enough to fit in a carry case or even in a closet.

Buy the bulk package and fill a couple of small cotton bags (or socks). These can be recycled at a low temp in your oven. Silicate packets are one of those things that you can't have too many of in high humidity conditions

Having water proof (weather sealed) cameras and lenses helps but still some precautions on your part will go a long way preventing fungus. First, take seriously the advise given by one of the members about the change in temperature going from an AC room to outdoors. Keep cameras and lenses in the camera bag and wait something like 15 minutes before beginning shooting. Keeping zip bags available is a great idea.
If raining the zip bags will prove invaluable. Even if the camera and lens are weather sealed I prefer more protection and I do not shoot under the rain if I can avoid it. Again, a zip bag is your best friend.
Remember that enemy No. 1 to fungus is sunlight but be very careful exposing camera and lenses to sunlight because that sunlight can cause damage to an optic and get the camera pretty hot. At the end of the day clean camera and lenses with a wet small towel after squeezing all the water from it. Then leave camera and lenses at room air till you use then again. Make sure you are in the room with your cameras or someone could "borrow" all or part of your gear.
Back home use a desiccant to remove any humidity left.

Why not rent what you would need?

If you are buying the packets, I see they come in 5 g and 10 g. What would be recommended for those little packets for your equipment
