C'mon, there is no such thing as a Singaporean accent. There are so many kinds of accents in Singapore. The one you mentioned is not even an 'accent' it is just broken English used by Mandarin speaking Singaporeans. Call a spade a spade, it is just illiteracy.
No such thing as a Singapore accent??? You have to be kidding. My sinkie detector picks up sinkies in a foreign land in less than 5 seconds. The accent is unmistakable. It stands out like a sore thumb.
Listen to the ladies in this video. These aren't illiterate sinkies. One of them may be a bit of a bimbo but "English" is pretty much her primary language and it's how most Singaporeans of her generation speak.
Notice how "need" becomes "nid", "something" becomes "samting", "through" is pronounced as "true", "make" becomes "mek", "think" becomes "tink" and so on.
One of the distinguishing characteristics of the Singapore accent is the lack of distinction between short and long vowels and the inability to pronounce "th" which invariably ends up being pronounced "d" or "t" depending on the context. Another unique feature is the lack of distinction between stressed and unstressed syllables as in "geography", "photography" and so on.
One of the biggest confusions I've witnessed personally was when a Singaporean lady was giving a demo on how to bake the Asian way. Nobody could understand what "flar" was. She repeated it over and over again throughout the demo. It was only when someone in the audience asked her to spell it did everyone realise she was saying "flour".
The Singapore accent is alive and well and is difficult for OZs and Kiwis to understand simply because they aren't used to it.
If you want to become a "citizen of the world", one of the first steps is to acknowledge the fact that EVERYONE has an accent. The "I don't have an accent" attitude is frog-in-a-well stuff at its very best.
