I just went to check some more TPE routes and it looks like either the fare has been pulled/replaced with something more expensive (but it doesn't look like it has, checking matrix?), or the AUD fell down a toilet against the New Taiwan Dollar somehow in the past week because everything is ~$200 aud more expensive
If you're willing to just fly back and forth between TPE-KUL-SIN and return, it looks like $1000 aud for 360 tier points, still not awful value, although I'm sure that at some stage, even authorities in SIN and TPE are going to start asking questions if you just literally fly back and forth trying to hit GGLfL or something
