Hi Ruben Krishnan,
If you're referring to listing your property in PropertyGuru Malaysia, then you'd need an agent to list for you as only certified Real Estate Agent (REA) or Real Estate Negotiator (REN) with an account on PropertyGuru Malaysia can post properties for sale or for rent here.
You could try getting in touch with agents in Terengganu. Those registered with PropertyGuru are listed here: https://www.propertyguru.com.my/property-agents/terengganu
. They might be able to assist you further.
Hope to see your property listed in this website soon!
