Low-cost carrier Jetstar will add six weekly services between Singapore and Perth from April 1.

The new services will bring the total number of flights a week offered by Jetstar between the two cities to 13.

Jetstar Asia chief executive Bara Pasupathi said in a statement on Monday that the airline's new schedule would allow for more Singaporean travellers to visit Perth.

Singaporeans make up the third biggest group of visitors to the Western Australian capital. Last year, Jetstar Asia carried more than 100,000 passengers between Singapore and Perth.
