Will buying SPDR S&P 500 ETF through SGX (S27) also incurr a 30% tax on the dividend?

Hi all, I am keen to invest in S&P 500 ETF and i know of the different options through my research.
1) buying through US market - subjected to 30% dividend tax and estate duties;
2) buying thru London or Irish domiciled S&P 500 ETF, and subjected to 15% tax on dividend;
3) buying through SGX SPDR S&P 500 ETF. However i am not sure if this option will be subjected to dividend taxes? is this ETF only for accredited investors?
