Last year, I included this in an email to undergraduate students reading my modules about post-exam activities. The honours students are winding own their field trips but opportunities still exist.
They need help with small mammal work, wild pig and otter surveys, measuring trees and other help in the field. This is a great way for undergraduates to gain exposure to field work and learn about nature areas in Singapore as well as how science is conducted in the field.
This is pretty much how I got started, following a researcher in the field. It certainly opens up a world to you.

The honours students will contact you once you register.
Your participation is also an opportunity to establish your reputation as a field worker and of your reliability, which will be useful in future opportunities.
