There has been some murmur of Asian-Pacific Rallies on here. Here are my thoughts...
Australia
At the moment, I think the rally will be staying in Coffs Harbour. Despite losing the iconic stages, it is really the only option. Tourism Western Australia no longer supported WRC, thus why it ended up moving, and I believe some of the forests have changed ownership, making it hard. Coffs Harbour isn't the best place, however, suitable forests which have "Australian" natured roads, near one of our big cities is hard to find. Western Australia is very unique, and it would take a bucket load of money to get it back there without the support of the government...
New Zealand
I don't think there is any doubt of it leaving the calendar, but it is very much a shrinking car market, when we look at the rest of the world, which is why I'm guessing its on rotation at the moment sadly. Running Australia and NZ back to back is a good idea though. There were talks back in 2002 of having a start in Europe, and spending considerable time out of Europe, before returning for the European summer for a couple of events, and then for Wales Rally GB at the end of the year. That could work well for the AUS/NZ combo.
Japan
Obviously the number 1 in the Asian market, so you'd want to be there. Hokkaido (APRC/WRC) did get a bit tired in the end, but it was a awesome rally when the Japanese manufacturers were there. With Subaru having announced a 1.6L WRX STI and Toyota showing interest, it wouldn't be a bad time to look into rallying there again. The Alpine Rally is another option, except based closer to Tokyo and not out in the Gunma region. Instead maybe west of Tokyo, where there are plenty of mountain passes. I can imagine it being a successful rally in Japan due to the 'Touge' style. So I'd be looking at Otsuki region. Cleaner and less out in the Styx which the Japanese may prefer, and a far bigger population base to work off with Tokyo.
Malaysia
Malaysia is very unique, similar to the old Indonesian WRC round except without the sandy base. The clay base when wet is diabolical! It runs very close to Kuala Lumpur too. So definitely a possibility. A very slow rally when wet, and certainly a big challenge for drivers. Getting numbers to this event is probably an issue, given that the Malay championship isn't huge.
China
It's been explored before, currently based a couple of hours away from Shanghai. Finding enough gravel roads would be tricky in that region, given they currently run stages on concrete town roads as well which would be far too fast for WRC cars!!! Could happen in the next decade as China continues to become a more developed economy.
Indonesia
Don't like its chances having been dropped from the APRC due to security concerns in Sulawesi. However, this is now a dry dusty rough rally, not the rally ran in the WRC. Small local championship too. The fact that Thailand has been re-introduced in the calendar for 2013, ahead of Indonesia speaks volumes, given Indonesia still has a bigger local championship.
Thailand
Having travelled to Phuket, I would very much doubt there would be a WRC rally there. Still getting there with development, and the gravel roads aren't graded that much. Currently, the Kings Cup Rally of Thailand is based an hour out of Bangkok, so pretty well placed, however, they do not have access to many roads (only 3-4 different stages reversed last year). Despite being a big builder of cars, Thailand again doesn't have the market for Euro brands considering how cheap it is to buy a Japanese car over there.
India
Hasn't been in the APRC for 7/8 years now. No local FIA homologated cars either.
