How much money do I need for a one month vacation to Koronadal City?

I am planning to visit my partner for one month in the Philippines. I am planning to stay within South Cotabato for the entire vacation with my partner. However, I am not entirely sure how much money is needed for the entirety of the trip. I have already paid for the tickets, and excluding the accommodation. I only would like to ask how much should I expect to be spending for the trip. Me and partner are not big spenders. I am planning to bring around 5000 aud (approx. 210,000 php) but I am still unsure if that is enough to cover the living expenses there.

Thank you very much. Any opinions are greatly appreciated.
