HFT, isn't widely available across Asia Stock Markets, except in Japan, IIRC. Is HFT in ASX widely used?

Published by the ASIC early last year, seems like its pretty prevalent in ASX.

Dark liquidity and high frequency trading

Findings
Our analysis showed that, while there is a considerable high-frequency trading presence in our markets – 27% of equity market turnover – the majority of it is done by 20 entities.
On the whole, we found that some of the commonly held negative perceptions about high-frequency trading appear to have been overstated, and were not supported by our findings. For example, the taskforce found that increases in order-to-trade ratios have been moderate compared with overseas markets, and have not been driven entirely by high-frequency trading.
Our analysis also showed that only 1.2% of high-frequency traders held positions for an average of two minutes or less, 18% for less than 10 minutes, and 51% for less than 30 minutes. This is contrary to the perception that holding times for high-frequency traders are typically a matter of seconds, or less.
We also found no evidence of systematic manipulation, or other predatory behaviours, from high-frequency traders, and while a number of discrete incidents required follow-up, these were the exception rather than the norm.
There was, however, some basis for the perception that high-frequency trading created excessive ‘noise’ in the market, although our analysis revealed that other traders using algorithms contributed to this problem.
