There is very limited knowledge of soil-transmitted helminths (STH) in Timor-Leste.
Contemporary quantitative PCR was used to assess STH and protozoa prevalence.
Water sanitation and hygiene (WASH) risk factors were analysed by age group.
High prevalence of STH was found, indicating a need for STH control strategies.
Few WASH factors emerged for STH or giardiasis, likely due to poor infrastructure.
