Looking for Legendary 4 aces ATV and Blowing in the Wind ATV

Desperately trying to find the last 18 episodes of Blowing in the Wind , in Cantonese , with Chen Quan Tai, Ma Mun Yee I got the first box set a few years ago to see if I would enjoy it ! AND I DID ! Was going to purchase the rest but unfortunately only the 2 box set was available , so got this but , the third was out of print and still is. :(

Also looked everywhere for The Legendary Four Aces, Michelle Yim, ATV series in Cantonese can only find it in Mandarin.

Region 4 disc (Australia) Can anyone help?
