Yes, that's very sad indeed considering that year ago there was 14 competitors (including two doubels). I checked how many Asians participating in WC/NC this season and it's not a big number: 3 women, 1 or 2 men (honestly I have no idea is Australia part of Asia in this sport) and 1 double. For comparison at the olympics there was 2 women, 3-4 men (Ferlazzo again) and 1 double. There was spots for host of course, but you don't have to qualify to NC so considering that in this season there is no luge competition in Asia (or maybe I just didn't hear about it) number of competitors in WC is very low.
Maybe something will change when juniors and youths will grow up. In this season there was only 4 juniors in WCJ (2 girls and 2 boys) but in youths it was 2 boys, 1 boys double, 1 girls double and... 5-7 girls! (one from Australia and one from New Zealand).
